Data Validation is pretty easy. Have you looked?
Would you say that an integer is a "whole number"?
If you are looking for a positive integer, would that be "greater than"
zero?

I have to enter rules for data for a cell that must have settings for
"positive integers" This is my first time using Excel. Any help would be
appreciated.
