curative instruction regarding the inapplicability of the felony murder rule.
We also find no merit in Nibert’s contention that his conviction should be reversed because of the trial court’s failure to give the jury written instructions. Ni-bert concedes that defense counsel did not request written instructions nor object to the trial court’s failure to provide them. Despite Nibert’s protestations to the contrary, the trial court’s failure to provide the jury with written instructions cannot be deemed fundamental error. Thus, because this issue was not properly preserved below, it was waived and may not be raised on appeal. See McCaskill v. State, 344 So.2d 1276 (Fla.1977).
Nibert’s argument that he was unconstitutionally tried by a death qualified jury has been previously rejected. See Lockhart v. McCree, 476 U.S. 162, 106 S.Ct. 1758, 90 L.Ed.2d 137 (1986); Kennedy v. Wainwright, 483 So.2d 424 (Fla.), cert. denied, — U.S. —, 107 S.Ct. 291, 93 L.Ed.2d 265 (1986).
We also disagree with Nibert’s contention that the trial judge erred in permitting the state’s tendered expert to testify as an expert witness. The trial court correctly admitted the testimony noting that the defendant’s objections related to the weight which should be accorded the testimony and not its admissibility.
Nibert’s argument that juror Stal-vey should have been excused for cause on the basis of her responses is likewise without merit. Moreover, although defense counsel did use a peremptory challenge to excuse Stalvey, he did not exhaust all of his peremptory challenges. Thus, even if the trial judge erred, in refusing to excuse Stalvey for cause, the error was harmless.
See Hill v. State, 477 So.2d 553, 556 (Fla.1985).
Finally, we find sufficient competent evidence to support a finding that the murder was premeditated. In Sireci v. State, 399 So.2d 964, 967 (Fla.1981), cert. denied, 456 U.S. 984, 102 S.Ct. 2257, 72 L.Ed.2d 862 (1982), we stated that:
Premeditation is a fully-formed conscious purpose to kill, which exists in the mind of the perpetrator for a sufficient length of time to permit of reflection, and in pursuance of which an act of killing ensues. Premeditation does not have to be contemplated for any particular period of time before the act, and may occur a moment before the act. (Citations omitted.)
We have further explained that circumstances indicative of a premeditated intent to kill include the manner in which the murder was committed and the type of wounds inflicted. See Welty v. State, 402 So.2d 1159, 1163 (Fla.1981). See also Mines v. State, 390 So.2d 332, 335 (Fla.1980), cert. denied, 451 U.S. 916, 101 S.Ct. 1994, 68 L.Ed.2d 308 (1981). The testimony of Andruskiewiecz that Nibert told him he had “made [the victim] get on his knees” during the stabbing in addition to the excessive number and nature of the wounds inflicted provides sufficient evidence to support a verdict that his death was the result of premeditated design.
As to his sentence, Nibert contends that the death penalty was improperly imposed because: 1) the trial court unlawfully delegated its duty to prepare an adequate statement of the findings to support imposition of the death penalty; 2) the judge instructed the jurors on the law prior to the taking of evidence and argument of counsel; 3) the trial court erred in failing to properly consider evidence pertaining to mitigating factors; 4) the trial court erred in finding the statutory aggravating circumstances of cold, calculated, and premeditated, and heinous, atrocious, and cruel; and 5) imposition of the death sentence imposed under these facts would violate the eighth amendment of the United States Constitution.
We reject Nibert’s argument that the death penalty was unlawfully imposed because the judge did not actually prepare the order of findings in support of the death sentence. The record reflects that the trial judge made the findings and conducted the weighing process necessary to satisfy the requirements of section 921.141,
