Try the following...

=SUMPRODUCT(--(A1:A100>="2/1/2005"+0),--(A1:A100<="2/28/2005"+0),B1:B100)

OR

=SUMPRODUCT(--(A1:A100>=C1),--(A1:A100<=D1),B1:B100)

...where C1 contains the start date, and D1 contains the end date.

Hope this helps!

I'm trying to establish a condition in a SumIf formula stating a range of dates.

e.g. Column A: Date, Column B: Cost

If the date in Column A is between 2/1/05 and 2/28/05, add expense from Column B.

I can only get it to add "later than" by indicating
=SUMIF('Men''s'!A4:FA93,">1/31/04",'Men''s'!B4:B293)
But that just adds up Column B ofr the rest of the year...

Any help's appreciated!
