Thanks for your help Pete. That works a treat.

As it is an array formula, Excel indicates this by means of the curly
braces { } around the formula when viewed in the formula bar. An array
formula must be committed using the key combination of CTRL-SHIFT-
ENTER (CSE) instead of the normal ENTER - do not type the curly braces
yourself.

So, once you have amended the formula, just use CSE to commit it
again.

Hope this helps.

I have used the conditional sum wizard to create a sum of a column for
period 1 based on certain criteria. I can copy this conditional sum to the
next column for period 2 using the same criteria, but of course it is working
out the sum based on period 1 column data. I tried to go into the fourmula
bar and change the column cell reference. This action deletes the {} at
front and back of the formula. When I type them in again. The function of
hte conditional sum formula is lost.

Is there a way to achieve what I am trying to do without having to use the
conditional sum wizard on every column?
