I used the following and got a #REF.
=SUMPRODUCT(SUMIF(INDIRECT("'"&6-1:6-90&"'!$N$8"),1,INDIRECT("'"&6-1:6-90&"'!$N$9")))

It also keeps taking the 0's out of my tab names...they are all in the
format 0#-0#
Could the tab names be a problem?

First, my assumptions which you will have to modify to suit your data

The cell to test is H1
The cell to accumulate is I1
There are three worksheets to test against

List the worksheets by name in M1:M3

Then use this formula

=SUMPRODUCT(SUMIF(INDIRECT("'"&M1:M3&"'!H1"),1,IND IRECT("'"&M1:M3&"'!I1")))

I have a workbook of about 30 pages.
I am trying to make a formula that will look at the same cell on each page
and if that cell has a value of "1" to sum another cell on only the pages
with the value "1".
I have tried, Sumproduct, Sumif, and have tried both of these with the
ThreeD function as well. I keep getting a VALUE error. Any suggestions?
