you can try this

=SUMPRODUCT(--(U2:U5="X"),--(T2:T5<J4),V2:V5)

I think something like this has been posted several times, but I can't seem
to get it to work with my application. I need to sum all cells in Col.V if
the adjacent cell in Col.U has a "X" in it AND if the date in Col.T is less
than the date in Summary!$J$4. For example, if Summary!$J$4 = 10/15/08 and
using the following data the function should return, 7.00.

The data is in a sheet named "Global Schedule"
Col.T Col.U Col.V
9/15/08 X 2.00
9/22/08 3.50
10/1/08 1.50
10/3/08 X 5.00

Thanks in Advance!
