Hi folks,
I'm pulling together the results of multiple questionaires taking the form
of a numeric answer (1-4). The responses have been pulled into a master
workbook and the all reside between marker tabs ("first" and "last").

Some formulas work OK across the range but not all. e.g
=SUM('first:last'!F4) returns a valid answer as do AVERAGE, COUNT and COUNTA

However COUNTIF or SUMIF all return #Value errors. It's not formatting or
bad input as the error still occurs when there is only 1 data sheet between
the marker tabs.

I suspect it may need an 'array' type formula but that's not a strong area
for me.

Can anyone give me a working COUNTIF formula?

Many thanks, Giz
