We find no error with respect to the main appeal. Accordingly, we affirm. As for the cross appeal, we agree with appel-lee that it was entitled to prejudgment interest; and we reverse the trial court’s denial of same and remand with direction to award it from January 81, 1982. See Argonaut Insurance Company v. May Plumbing Company, 474 So.2d 212 (Fla. 1985), approving Bergen Brunswig Corporation v.
