Peter,
What through the formula is that the cell had been custom formatted. I have
now changed the formula to:
=IF(AND(I87-J870,S87=1),0,I87-J87)
Thanks

Hi,
the "yes" in the formula needs to be double quoted...
the yes in cell s87 does not.

The following formula is not doing what it is supposed
to be doing:

=IF(AND(I87-J870,S87="Yes"),0,I87-J87)

A value should only be returned if S87="Yes"

What happens is a value is returned regardless if
S87="Yes" or not. Anyone
know what is wrong here?

Thanks
Pat
