Alright uing $'s worked for keeping things from moving around. New post! I
have a formula in a multiple / 100's of cells like this.

=SUMPRODUCT((Sheet1!$A$2:$A$4=3)*(Sheet1!$B$2:$B$4 =300)*(Sheet1!$C$2:$C$4={"C","P","S","T"})*Sheet1! $E$2:$E$4)

I want to change the first array value from =3 to =039 in all of them in one
worksheet at a time. Is there an easy way of this or is it going to be a one
by one process. Thanks for everyones help so far, and Thanks for the replies
in advance on this one.
