ROSE, Justice.
Appellant-plaintiff Donald Burton (Burton) brought suit against Fisher Controls Company (Fisher), H & H Services, Inc. (H & H), Olman-Heath Company (Olman-Heath), G. Wayne Pierce, dba Pierce Construction Company (Pierce), and A.J. Deans (Deans) for damages resulting from a gas-regulator explosion. Liability against Fisher was predicated upon negligent design of the regulator; against H & H for negligence flowing from the sale and installation of the regulator; against Olman-Heath for negligent installation of the regulator and failure to install safety devices, and for negligence in turning high-pressure gas into the regulator and failing to warn Burton of these allegedly dangerous conditions; against Pierce for failing to take corrective action at the well site and failing to warn Burton of the existing dangerous condition; and, finally, against co-employee Deans for gross negligence.
All defendants answered, denying liability and alleging contributory negligence on the part of Burton. H & H was granted summary judgment, and, while an appeal was being taken, Burton settled his claim with H & H and the appeal was dismissed. Prior to trial, Fisher and Pierce settled the claims against them, and therefore trial was had against Olman-Heath and Deans only.
The record reveals that, throughout the trial and in the instructions and verdict form, the court identified and referred to Fisher and Pierce as “Defendants” along with Olman-Heath and Deans, even though Fisher and Pierce had settled with the plaintiff, had been dismissed from the case, and thus were no longer parties defendant. The record discloses that, prior to trial, plaintiff requested that Fisher and Pierce not be referred to as “Defendants” to the jury. The court refused this request, and, in its introductory remarks to the jury, indicated that Fisher and Pierce, along with Olman-Heath and Deans, were defendants in the case. Furthermore, as will be seen, the trial court, in Instruction No. 20, admonished the jury that Fisher and Pierce would be liable to Burton in the event the jury found their liability to be in excess of any negligence which the jury found attributable to the plaintiff.
At the close of all of the evidence, a motion for directed verdict was granted in favor of Deans on the issue of gross negligence. The jury thereafter returned a verdict in favor of Olman-Heath and found no negligence attributable to either Fisher or Pierce.
We will reverse the trial court. This being our decision, we find it necessary to [1139]*1139consider only the following issues as identified by the appellant:
1. “Did the trial court err in granting a directed verdict on the issue of gross negligence in favor of co-employee defendant A.J. Deans when evidence of Deans’ gross negligence upon which reasonable men might differ was presented to the jury?”
2. “Was it fundamental error for the trial judge to instruct the jury that plaintiff was still making a claim against defendants with whom plaintiff had previously settled?”
ISSUE NO. 1
Gross Negligence and Deans’ Directed Verdict
Motions for directed verdicts should be cautiously and sparingly granted. Vassos v. Roussalis, Wyo., 658 P.2d 1284 (1983).
In reviewing the propriety of a directed verdict, we must consider all of the evidence favorable to appellant and give it every reasonable inference which may be drawn. If the evidence, when viewed in this light, can reasonably support more than one conclusion, the directed verdict will be said to have been erroneously granted. Town of Jackson v. Shaw, Wyo., 569 P.2d 1246 (1977).
In Town of Jackson, we said:
“In reviewing the grant of a directed verdict by a trial court, consideration must be given to all evidence favorable to party against whom the motion is directed, as well as tó all reasonable and legitimate inferences which might be drawn therefrom. McCarthy v. Croker, Wyo. 1976, 549 P.2d 323; Barnes v. Fernandez, Wyo. 1974, 526 P.2d 983; Brennan v. Laramie Newspapers, Inc., Wyo. 1972, 493 P.2d 1044.. Whether or not the evidence so viewed is sufficient to create an issue for the jury is solely a question of law to be answered by the trial court. That court must determine whether or not the evidence is such that, without weighing the credibility of the witnesses, or otherwise, considering the weight of the evidence, there is but one conclusion as to verdict which men of reason could reach. Barnes v. Fernandez, supra. * * *” 569 P.2d at 1250.
We turn, then, to this court’s definitions of gross negligence and the applicable facts and inferences which are the most favorable to appellant to see whether, under the Town of Jackson v. Shaw guidelines, the court erred in directing the verdict in favor of Deans.
In Mitchell v. Walters, 55 Wyo. 317, 330, 100 P.2d 102 (1940), this court accepted the definition of gross negligence which Chief Justice Rugg of the Massachusetts Supreme Judicial Court authored in Altman v. Aronson, 231 Mass. 588, 121 N.E. 505, 506, 4 A.L.R. 1185 (1919), where the Chief Justice said:
“ ‘Gross negligence is a manifestly smaller amount of watchfulness and circumspection than the circumstances require of a person of ordinary prudence. But it is something less than the wilful, wanton and reckless conduct which renders a defendant who has injured another liable to the latter, even though guilty of contributory negligence, or which renders a defendant in rightful possession of real estate liable to a trespasser whom he has injured. It falls short of being such reckless disregard of probable consequences as is equivalent to a wilful and intentional wrong. Ordinary and gross negligence differ in degree of inattention, while both differ in kind from wilful and intentional conduct which is, or ought to be, known to have a tendency to injure. This definition does not possess the exactness of a mathematical demonstration, but it is what the law now affords.’ ”
We have been comfortable with this definition of gross negligence down through the years. See Danculovich v. Brown, Wyo., 593 P.2d 187 (1979); Sanders v. Pitner, Wyo., 508 P.2d 602 (1973); Moore v. Kondziela, Wyo., 405 P.2d 788 (1965).
Some of the relevant facts most favorable to appellant which must be tested against these concepts of gross negligence [1140]*1140for purposes of determining whether the court erred in directing a verdict in Deans’ favor are these:
Pierce, an independent contractor for Davis Oil, testified that he considered the elevated pressures in the well to be dangerous and that he reported these pressure levels to Deans:

H & H was granted summary judgment, and, while an appeal was being taken, Burton settled his claim with H & H and the appeal was dismissed.

ISSUE NO. 1
Gross Negligence and Deans’ Directed Verdict
Motions for directed verdicts should be cautiously and sparingly granted. Vassos v. Roussalis, Wyo., 658 P.2d 1284 (1983).
In reviewing the propriety of a directed verdict, we must consider all of the evidence favorable to appellant and give it every reasonable inference which may be drawn. If the evidence, when viewed in this light, can reasonably support more than one conclusion, the directed verdict will be said to have been erroneously granted. Town of Jackson v.

We turn, then, to this court’s definitions of gross negligence and the applicable facts and inferences which are the most favorable to appellant to see whether, under the Town of Jackson v. Shaw guidelines, the court erred in directing the verdict in favor of Deans.
In Mitchell v. Walters, 55 Wyo. 317, 330, 100 P.2d 102 (1940), this court accepted the definition of gross negligence which Chief Justice Rugg of the Massachusetts Supreme Judicial Court authored in Altman v. Aronson, 231 Mass. 588, 121 N.E. 505, 506, 4 A.L.R. 1185 (1919), where the Chief Justice said:
“ ‘Gross negligence is a manifestly smaller amount of watchfulness and circumspection than the circumstances require of a person of ordinary prudence. But it is something less than the wilful, wanton and reckless conduct which renders a defendant who has injured another liable to the latter, even though guilty of contributory negligence, or which renders a defendant in rightful possession of real estate liable to a trespasser whom he has injured. It falls short of being such reckless disregard of probable consequences as is equivalent to a wilful and intentional wrong. Ordinary and gross negligence differ in degree of inattention, while both differ in kind from wilful and intentional conduct which is, or ought to be, known to have a tendency to injure. This definition does not possess the exactness of a mathematical demonstration, but it is what the law now affords.’ ”
We have been comfortable with this definition of gross negligence down through the years. See Danculovich v. Brown, Wyo., 593 P.2d 187 (1979); Sanders v. Pitner, Wyo., 508 P.2d 602 (1973); Moore v. Kondziela, Wyo., 405 P.2d 788 (1965).
Some of the relevant facts most favorable to appellant which must be tested against these concepts of gross negligence [1140]*1140for purposes of determining whether the court erred in directing a verdict in Deans’ favor are these:
Pierce, an independent contractor for Davis Oil, testified that he considered the elevated pressures in the well to be dangerous and that he reported these pressure levels to Deans:
“Q. Mr. Pierce, didn't it bother you that the pressures in the well were as high as they were?
“A. It concerned me.
“Q. And I want you to tell the jury in your own words why it concerns you? “A. Because as far as I was concerned it was becoming an unsafe condition. “Q. You thought it was dangerous?
“A. I thought it was dangerous.
“Q. And for that reason did you have anything that you did with your employees; in other words, did you permit your employees to go to that well or did you go there yourself?
“A. I did it myself.
“Q. And what was the reason you did it yourself instead of sending your employees?
“A. They were scared of it, they were scared of the high pressure, so I just took it on myself to do it myself. I wouldn’t ask them to do something that I wouldn’t do.
“Q. And when you found out about this pressure, did you do anything to notify the Davis Company?
“A. Yes.
“Q. What did you do?
“A. I phoned in the pressures to A.J. Deans every morning.
“Q. Every morning?
“A. Reporting the increase in pressures.
“Q. To Mr. Deans?
“A. Yes.”
On the morning of the explosion, Pierce told Deans that he would no longer relieve pressures in the well:
“Q. Did you tell Mr. Deans that you weren’t going to blow the well down anymore, that you didn’t want to be there anymore?
“A. I said that I would blow it down today, but that would be my last time. “Q. Did you tell him — why was that? Why did you say that?
“A. I guess I’m a coward.”
Deans denied receiving the reports of increasing pressures in the well from Pierce, but testified that accounts of dangerously high pressures would have triggered an immediate response on his part:
“Q. [By Mr. Meyer] If Mr. Pierce had called you and said the things to you that he said he said about the pressures in the well, wouldn’t you have had a responsibility to take some immediate action?
“A. I believe so, yes, sir.
“Q. And it would have been completely improper under the circumstances not for you to have done something; isn’t that right?
“A. If I thought it was getting dangerous, yes, sir, we would do something.
"Q. And if you didn’t it would have been completely improper on your part; isn’t that right?
“A. I think most anybody, yes, sir.
“Q. And you kind of — the action you would have taken would have been to go out and immediately make the well safe; isn’t that right?
“A. You’d — you’d appraise the situation and figure a course of action, yes, sir.
“Q. But you did nothing at all?
“A. We didn’t consider it dangerous, sir.”
Given the testimony of Deans and Pierce and all other favorable evidence of record, together with all reasonable inferences to be drawn therefrom, we hold that the evidence would be sufficient to support a finding of gross negligence — had that been the decision of the fact finder. Deans knew of the increasing pressures in the well and knew or should have known of the danger, and he neither took corrective measures nor warned workers of the unsafe conditions. These facts are adequate for purposes of structuring an issue for the jury [1141]*1141and sufficient to remove the question as being one of law for the court. The trial court therefore erred when it directed the verdict in favor of Deans on the issue of his gross negligence.
ISSUE NO. 2
Was It Error for the Trial Court To Treat Fisher and Pierce with Whom The Plaintiff Had Settled As Remaining in the Case As “Defendants”?
Burton contends that the trial court committed reversible error in informing the jury that Fisher and Pierce remained in the case as “Defendants” with potential liability to the plaintiff, even though they had settled the claims against them and had been dismissed prior to trial.
Specifically, appellant attributes error to the trial court’s reference to Fisher and Pierce as “Defendants” in Instruction No. 2. That instruction provides in part:
“INSTRUCTION NO. 2
“Donald Burton, plaintiff herein, claims damages for injuries he claims he sustained as the result of an accident which occurred on March 8, 1977. Burton will hereinafter be called ‘Burton’ or ‘Plaintiff’, and Fisher Controls Company, a corporation, Olman-Heath, a corporation, A.J. Deans and G. Wayne Pierce, dba Pierce Construction Company will hereinafter be called ‘Fisher’, ‘Olman’, ‘Deans’ and ‘Pierce’ individually, or collectively for convenience, as ‘Defendants ’.
“It has been claimed that all of the above were guilty of negligence, and that such negligence, sometimes hereinafter called ‘fault’, was either wholly or partially, a direct cause of the accident and of any injuries and damages sustained by Burton.” (Emphasis added.)
Burton also complains of Instruction No. 20 which informed the jury that any “Defendant” (which, under Instruction No. 2, included Fisher and Pierce) whose fault exceeded that of the plaintiff would be liable in damages. This instruction reads as follows:
“INSTRUCTION NO. 20
* * * * * *
“If you find that Burton, and any of the Defendants were at fault, and that Burton’s degree of fault was equal to or greater than the fault of any Defendant, then that Defendant will not be liable to Burton. However, if you find that the degree of fault of any Defendant was greater than Burton’s degree of fault, then that Defendant will be liable to Burton.” (Emphasis added.)
For purposes of this discussion, Instruction No. 20, when read with Instruction No. 2, says that if the jury is able to find the negligence of Pierce and/or Fisher to be greater than the negligence of Burton, then Pierce and/or Fisher would be liable to Burton.
Appellant also contests the verdict form — not because Pierce and Fisher were included in the list of participants, but because they are designated as “Defendants.”1
[1142]*1142Appellant points out in his brief that these references to Fisher and Pierce as “Defendants” in the instructions and the verdict form misinformed and misled the jury as to those who were properly before the court for the purpose of ascertaining liability to the plaintiff, and further argues that the jury was thereby invited to speculate as to the status of Fisher and Pierce and Burton’s reasons for producing no evidence against them. In his brief, the appellant contends:
“The instructions, as given, falsely informed the jury that Fisher and Pierce were defendants and that plaintiff was making claim against them. Since the issues with Fisher and Pierce had been settled prior to trial, neither of them appeared through counsel or offered any evidence. Nor did plaintiff produce any evidence since to do so would only have diminished plaintiffs claims against the remaining defendants at trial. This left the plaintiff in the unenviable and prejudicial position of appearing to be making claims against Fisher and Pierce, but being unable or unwilling to produce any evidence against them. * * * What must the jury have believed? That plaintiff had sued Fisher and that they were a defendant in this case but that plaintiff was unwilling to present evidence against them? Such a situation could only invite the jury to speculate as to non-existent circumstances. The credibility of plaintiff’s entire case was totally compromised. * * * ”
Of even greater importance is the fact that the submitted instructions and jury verdict repeatedly treat Fisher and Pierce as parties defendant who were having their negligence compared for liability purposes, and therefore the jury directions contained erroneous and misleading information as to the consequences of the jury’s verdict.
The Effect of Misinforming the Jury Of the Consequences of Its Verdict
Through Instruction No. 20, supra, the jury was told that “any Defendant” (which would include Fisher and Pierce since they were identified as “Defendants” in Instruction No. 2, and as “parties” in the verdict form) would be liable to Burton in damages if their degree or degrees of fault exceeded Burton’s degree of fault. By failing to distinguish between those actors who remained in the litigation as parties for the purpose of ascertaining liability (if any) and those who had been dismissed and were [1143]*1143required to be included upon the jury form for comparative-negligence and contribution purposes only, the court incorrectly instructed the jury that its verdict could result in liability for participants who had settled with the plaintiff prior to trial. This, of course, is not the law.
The Law Pertaining to the Proposition That Settling Tortfeasors May Never Remain Liable To the Plaintiff, or, for That Matter, To Any Actor Including the Remaining Defendants
Comparative Negligence
While settling actors cannot be designated in the instructions or verdict form as “defendants” or “parties,” it is readily conceded that, under our comparative-negligence statute, § 1-1-109, W.S. 1977,2 it is imperative for the court to include settling causative participants, such as Fisher and Pierce, on the jury form.3 This is so because, in a comparative-negligence case where relative fault is in issue, the jury must not only consider causative negligence of the parties to the litigation, but it must also ascertain the percentage of fault for all of the participants in the tortious conduct which causes injury. Kirby Building Systems v. Mineral Explorations Company, Wyo., 704 P.2d 1266 (1985); Board of County commissioners of County of Campbell v. Ridenour, Wyo., 623 P.2d 1174 (1981). This identification of each actor’s share of the total causative fault is necessary to a valid comparison between the plaintiffs negligence and the negligence of each defendant. Kirby Building Systems v. Mineral Explorations Company, supra; Board of County Commissioners of County of Campbell v. Ridenour, supra. Accord Palmeno v. Cashen, Wyo., 627 P.2d 163 (1981). Under § l-l-109(a), supra note 2, the plaintiff can recover only from those defendants whose negligence exceeds his own, and for that calculation to be made, 100 per cent of the causative fault must be included in the formula.
In Kirby Building Systems, we summed up these comparative-negligence concepts having to do with the necessity of and reasons for including nonparty actors on the verdict form, and we went on to explain that, even though it was necessary to include nonparty actors on the verdict form, the nonparty was not bound by the degree of fault fixed by the jury, and the nonparty actor’s negligence is not to be compared with the negligence of a party. That rule is diametrically opposed to Instruction No. 20 given by the trial court in this case.
In Kirby Building Systems, supra, 704 P.2d at 1272-1273, we said:
“Even though the nonparty actors’ percentage of negligence must be ascertained so that the parties’percentage of negligence may be accurately disclosed, the nonparty actor is, of course, not bound by the degree of fault fixed by the jury, Board of County Commissioners of Campbell County v. Ridenour, supra, nor does the nonparty actor have any direct influence upon any [1144]*1144party’s ability to recover in the action. The nonparty actor’s negligence is not compared with the negligence of the party, because recovery is not sought from a nonparty. The nonparty actor does, however, influence the comparison process in the sense that his fault is contemplated along with the fault of the parties for purposes of determining whether the plaintiff may recover from a defendant or from defendants for the injury for which recovery is sought. Board of County Commissioners of Campbell County v. Ridenour, supra. Logic dictates that, if the negligence of an actor who is not a party is not included in the comparative-negligence calculation, the percentage of negligence of defendants who are parties may be inflated, and this would have a detrimental impact upon the comparison of the fault of the plaintiff and the several defendants in reaching a determination as to liability of some or all of the defendants to the plaintiff.” (Emphasis added.)
For purposes of resolving the comparative-negligence question in the case at bar, these lessons from Ridenour and Kirby Building Systems teach that Fisher and Pierce must indeed appear upon the verdict form “so that the parties’ percentage of negligence may be accurately disclosed,” Kirby Building Systems, supra, 704 P.2d at 1272, but, contrary to the trial court’s instruction here, “the nonparty actor’s negligence is not compared with the negligence of a party because recovery is not sought from a nonparty.” Id.
Necessity for All Actors To Be on the Verdict Form For Contribution Purposes
Contribution Among Joint Tortfeasors
While it was error for the trial court to refer to settling participants Fisher and Pierce as “parties” and “defendants,” it was nonetheless necessary that they appear on the verdict form — not only to establish an accurate reading of the totality of the causative negligence for comparative-negligence purposes, but also because their inclusion upon the verdict could have been important for contribution-among-joint-tortfeasors requirements.4 We said in Kirby Building Systems, supra, 704 P.2d at 1275-1276:
“In pursuit of the policy described by the legislature, settlements are made attractive in that a nonsettling tortfeasor may not collect contribution from a fault-contributing actor who has settled with the plaintiff,
“The settlement will not discharge any actor except the settling tortfeasor unless the terms so provide. Section 1-1-113(a)(i). Any amount the plaintiff receives over and above his judgment may be retained by the plaintiff, but, of course, if the plaintiff were to receive an amount of money in settlement that exceeds the amount of his judgment, he would not be entitled to recover anything further on his judgment.
“From the foregoing, it appears clear that the policy of comparative negligence, which seeks to eliminate the unjust concept of common-law contributory negligence by permitting negligent plaintiffs to recover from more negligent tort-feasors, cannot be discharged unless the burden among tortfeasors other than the plaintiff is also distributed equitably under the Right to Contribution Among Joint Tortfeasors statutes.”
Resolution of the Question Which Asks:
Given the law of contribution among joint tortfeasors and comparative negligence, is it error for the trial court to instruct the jury that settling tortfeasors remain in the case for the purpose of settling contribution and comparative-negligence issues?
The answer is yes.
An affirmative answer is mandated because, under the authorities and statutes set out above, negligence can never be assigned to a nonparty, as the jury was instructed to do in this case, for the purpose of ascertaining the nonparty’s liability to the plaintiff or to any party or nonparty — nor can a settling tortfeasor be represented to the jury as a party for contribution-among-joint-tortfeasors purposes.
One who is not a party to a lawsuit cannot be bound by the fact finder’s determination of his degree of fault. Kirby Building Systems v. Mineral Explorations Company, supra; Palmeno v. Cashen, supra; Board of County Commissioners of County of Campbell v. Ridenour, supra. Further, under § 1 — 1—113(a)(ii), W.S.1977, a nonparty who has entered into a settlement agreement with the plaintiff cannot be held liable, even in a separate action, for contribution to the other tort-feasors. Nonparties appear on the verdict form solely for the purpose of allocating negligence among all tortfeasors so that liabilities among tortfeasors who are parties to the action may be properly ascertained, and so that statutory contribution responsibilities may be later identified.
The trial court in the instant case instructed the jury that its apportionment of negligence could result in liability for alleged tortfeasors who had settled with plaintiff-appellant Burton prior to trial. The instructions, therefore, misinformed the jury as to the consequences of its verdict.
[1146]*1146
To Misinform the Jury Concerning The Consequences of Its Verdict Is Error
Under Wyoming statutes, the jury must receive accurate information concerning the consequences of its verdict. Section 1-1-114, W.S.1977, provides in part:
“ * * * In all cases the court shall inform the jury of the consequences of its verdict.”
Section 1 — 1—109(b)(iii), W.S.1977, states the rule for comparative-negligence cases:
“(b) The court may, and when requested by any party shall:
* ⅜ * 3⅜ * #
“(iii) Inform the jury of the consequences of its determination of the percentage of negligence.”
We held in Johnson v. Safeway Stores, Inc., Wyo., 568 P.2d 908 (1977), that this duty devolves upon the court even though the plaintiff's counsel does not request it. In so holding, we relied upon Appelgren v. Agri Chem, Inc., Colo.App., 562 P.2d 766 (1977), where the Colorado Court of Appeals, in interpreting the same provision as that contained in our § 1-1-114, supra, held that the word “shall” as employed in the statute is mandatory. In Woodward v. Haney, Wyo., 564 P.2d 844, 847 n.4 (1977), Justice Raper wrote for the court:
“ * * * If the jury is to be informed of the effect of its verdict, it ought to be correctly informed to the fullest extent.
* sfc * ))
In general, when instructions tend to confuse or mislead the jury concerning applicable principles of the law, reversal is proper. Cervelli v. Graves, Wyo., 661 P.2d 1032 (1983).
The instructions and verdict form in this case misinformed the jury concerning the parties that were actually before the court for comparative-negligence purposes. We said in Cervelli v. Graves, supra, 661 P.2d at 1040, that incorrect and misleading jury instructions prejudice the parties and require reversal:
“ * * * What a jury may decide upon hearing this case and after being properly instructed we are unable to say. What we must say, though, is that appellant should have the benefit of having his case decided by a properly instructed jury rather than by the trial court through an incorrect jury instruction.”
Reversed and remanded for a new trial.
5. Section 1-1-113(a)(ii), W.S.1977, provides:
"(a) When a release or a covenant not to sue or not to enforce judgment is given in good faith to one (1) of two (2) or more persons liable in tort for the same injury or the same wrongful death:
******
"(ii) It discharges the tortfeasor to whom it is given from all liability for contribution to any other tortfeasor."
