Try this, Connie:

=IF(ISNA(MATCH(A2,Sheet1!C:C,0)),"No","Yes")

then copy down as required.

Hope this helps.

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
