Hi,

On *sheet2 of Book1*, Column C has two-character codes; Column M has
dates; Column R has $ amounts; and Column X has dates.

On *Sheet1 of Book2*, I want the total from Column R for code AB where
the *month* in Column M is less than the *date* in Column X.

I try the following formula:

=SUMPRODUCT(--('[Book1.xls]Sheet2'!C4:C1550="AB"),--(MONTH(DATE(YEAR('[Book1.xls]Sheet2'!M4:M1550),MONTH('[Book1.xls]Sheet2'!M4:M1550),DAY('[Book1.xls]Sheet2'!M4:M1550)))<MONTH(DATE(YEAR('[Book1.xls]Sheet2'!X4:X1550),MONTH('[Book1.xls]Sheet2'!X4:X1550),DAY('[Book1.xls]Sheet2'!X4:X1550)))),'[Book1.xls]Sheet2'!R4:R1550)

but it giving #VALUE! error.

Any help?

Thank you,
Gos-C
