Hi,
Excel 2000 question
I have a Workbook with two sheets "Daily" and "Clients".

In Daily sheet col F
I want a formul in F2 that will look in col B2 and tell me if the name
in B2 is in Col A2:A200 of sheet the Clients sheet.
Example: this only gives me No. and the name in B2 is in Col A of the
Clients sheet.
IF(B2='Clients'!A1:A200,"Yes","No")

Thanks,
JK
