I can't get this to work in the right formula context. Can you help me
with the formula?
Well, I don't have much info from you. I was thinking:
=SUBTOTAL(109,INDIRECT("PrintData!B"&RowIndex&":"&"PrintData!B"
&RowIndex))
I think that should work, but you'll have to put in your reference in
the Indirect function. If you don't know how Subtotal works, look it
up in Help. There are several calculations it can perform, you change
the "109" to the one you need. Help lists the options.
