Here's an alternative that will work on all of the machines:

=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(E12&":"&AU12)),2)<6),--(ISNA(MATCH(ROW(INDIRECT(E12&":"&AU12)),$A$1:$A$9, 0))))

I created a network days formula that excludes holidays,
=NETWORKDAYS(E12,AU12,$A$1:$A$9). Saved on a spreadsheet in a shared
file.

Works on my computer when I am logged in.

Doesn't work (get the 'name' error):
-on other computers when I am logged in
-on other computer when someone else is logged in
-on my computer when someone else is logged in

All computers have same 2003 version of Excel.

Any ideas?? I'm stumped!
