Dev. Agency, 716 S.W.2d 856, 859 (Mo.App.1986). Finally, the point fails because appellants sought no relief from the court, either for a mistrial, for an order striking the comment or for instruction that the jury disregard the comment. Where there is no objection until after the questioned matter is before the jury, it is incumbent on the objecting party to move for specific relief after the objection has been overruled. Failure to do so waives the asserted error. Kilgore v. Linville, 733 S.W.2d 62, 64-65 (Mo.App.1987).
Appellants’ fifth point is denied, it being also noted that despite the foregoing deficiencies, we find no demonstrable prejudice to the appellants from the quoted remark.
The sixth point contends the trial court erred in failing to direct a verdict for the plaintiffs at the close of the evidence.
It is seldom, if ever, that a trial court should direct a verdict for the party having the burden of proof. State ex rel. State Highway Comm’n v. Gebhardt, 714 S.W. 2d 558, 560 (Mo.App.1986). A court ordinarily is not justified in directing a verdict for the party having the burden of proof if the evidence relied on consists of oral testimony. Hodges v. Hodges, 692 S.W.2d 361, 366 (Mo.App.1985). In a negligence case depending on oral testimony, an exception to the rule precluding the direction of a verdict for the plaintiff arises only where the defendant admits or by his evidence establishes plaintiffs claim or, where there is no real dispute as to the basic facts supported by uneontradicted testimony. Zagarri v. Nichols, 429 S.W.2d 758, 760 (Mo.1968).
The basic issue in the present case was whether Dr. Spencer was negligent in that the treatment he rendered to Mrs. Reed was not performed with the degree of skill and learning ordinarily used under the same or similar circumstances by members of the medical profession. That determination depended on opinion evidence as well as the evidence of Mrs. Reed’s physical condition and the treatment procedures Dr. Spencer employed. There was sharp conflict of opinion on the essential elements of the case. Dr. Spencer certainly did not admit negligence and in most respects, the issues in the case were disputed. There was no conceivable basis for the court to have directed a plaintiffs’ verdict because tjie defendants’ evidence did not establish plaintiffs’ claim and the basic facts on which the decision turned were disputed and were therefore not proved by uncontra-dicted testimony. The point is denied.
In a final point, appellants present a dual argument directed to the general complaint that the trial court unjustifiably undertook to expedite the proceedings. They first contend that in this framework of prejudice, even if the previous six points of error alone are not sufficient to warrant a new trial, the cumulative effect is enough to require that relief. They cite Faught v. Washam, 329 S.W.2d 588, 604 (Mo.1959), where it is said, “Without undertaking to determine whether any single matter ..., standing alone, would constitute reversible error [citations omitted], we are firmly of the opinion that, in their totality, they do.”
Under the constraints of § 512.160.2, RSMo 1986, an appellate court is not to reverse a judgment for error unless some injury has been worked upon the complainant. State v. Armstrong, 605 S.W.2d 526, 530 (Mo.App.1980). Thus, every instance of trial error does not entitle an appellant tp prevail. Only where prejudice is demonstrated will the judgment be reversed. The concept exemplified in Faught is an application of this rule indicating that the aggregation of errors may produce a cumulative effect of prejudice where individually, the prejudice is insufficient to justify reversal.
The principle is of no aid to appellants here. If the issue of prejudice, singly or collectively, is to be considered, there must first have been some error committed in the trial. In the six points of alleged trial error already discussed in this opinion, we have either concluded there was no error or, if error was present, it was not preserved for appellate review. There cannot be an argument advanced based on accumulated prejudice if there has been no underlying error in the trial. Such is the case here.
