The MONTH function doesn't care which sheet it's referring to.

Anyway, perhaps one of these variations:

=IF(MONTH(Monthly!N10)=MONTH(Sheet1!A5),Monthly!N2 0,IF(MONTH(Monthly!M10)=MONTH(Sheet1!A5),Monthly!M 20,"xxx"))

or

=CHOOSE(SUMPRODUCT((MONTH(Monthly!M10:N10)=MONTH(A 5))*{1,2})+1,"xxx",Monthly!M20,Monthly!N20)

or...

=CHOOSE(SUMPRODUCT((TEXT(Monthly!M10:N10,"yyyymm") =TEXT(A5,"yyyymm"))*{1,2})+1,"xxx",Monthly!M20,Mon thly!N20)

Note: in case text wrap impacts the display, there are NO spaces in those
formulas.

Does that help?

for some reason the month function doesn't seem to work between links of
separate worksheets.

I changed the formula to this:

=IF(EOMONTH(Monthly!N10,0)=EOMONTH(A5,0),Monthly!N 20,IF(EOMONTH(Monthly!M10,0)=EOMONTH(A5,0),Monthly !M20,"xxx"))

and it works now, but if you know of a better way, I'd like to hear.

Thanks again.

Try this
=1+(MONTH(A1)<9)

cell a1 = the date

a1 could equal 9/15/2007, 8/20/2007, 9/26/2007, 5/30/2006, etc.

formula please?:

if the date in cell a1 falls in the month of september, then "1",
otherwise
"2"

thanks very much!
