This is my countifs function:
=COUNTIFS(Oct2009!$AV$2:$BG$3009,$A2,Oct2009!$AV$2:$BG$3009,E$1)
Either one of these works. That is:
=COUNTIFS(Oct2009!$AV$2:$BG$3009)
produces 110 and
=COUNTIFS(Oct2009!$AV$2:$BG$3009,E$1)
produces 2295
I was thinking those combined criteria would count the matches in the 2nd formula agaist those of the first, or at least, that's the way I interpret the docs.
Am I clear enough?
