I'm trying to create a formula for the following
conditions:

column J Column I Column E
Month: Billed: Revenue:
12/1/2004 x 5,000
11/1/2004 2,500
10/1/2004 x 1,000
10/1/2004 2,000
1/1/2005 3,000
1/1/2005 x 4,000

So I want the formula to look at if the month is October
(or 10/1/2004) & if it was billed (x), then sum the
revenue column.

This is the formula that I tried, but it is still coming
back with a $0 answer:

=SUMPRODUCT((J5:J44="10/1/2004")*(I5:I44="x")*(E5:E44))
The result should be $1,000

I've tried to enter the formula exactly as it is written
& I've tried to enter the formula as an array by doing
CTRL+SHIFT+ENTER, but I still get $0

What am I doing wrong?, or if there is a better formula
to use...

Thanks!
