This is a simple formula, I know, and I wish the formula wizard was simple,
too!! Can't get it, so I need someone's help.

In cell C1 in Sheet2 I need a formula that will look at the numbers in Col.
A in the same worksheet and see if the number is in Col. C of Sheet1, and
return "Yes" if it is, and "No" if it isn't. Simple enough, I think. Thank
you. Connie
