=SUM('Q1:Q13'!A1)

Put the single quotes in yourself. Without them, I suspect Excel gets
confused thinking this is a cell reference rather than a sheet name. Worked
for me.

I'm trying to count then occurences of "C" in the same column on 13
different worksheets (same workbook) named Q1 to Q13. I did a countif
on each sheet, then entered the following formula in a summary sheet:
=sum(Q1:Q13!C65)
I'm getting a #VALUE error because XL keeps inserting single quotes
into my formula so it becomes
=sum(Q1:'Q13'!C65)

Does anyone know why XL is editing my forumla this way? Is there a
workaround?
Thanks.
