Hi Gary, thanks for the reply. I tried the formula, but came up with a
"#VALUE!".
My dates are in column AD (AD2:AD109)
My Prices are in column I (I2:I109)
I need the sum of prices between:
1/1/07 (located at AI48). Number value is 39083.
and
5/31/09 (located at AI49). Number value is 39964.
Here is your formula after it's been plugged in.
=SUMPRODUCT(--(AD2:AD109>=AI48),--(AD2:AD109<=AI49),--(I2:I109))
Where did I go wrong?
