Hello,

It's not working. The results are all zero.

What can be wrong?

Thanks.

Assuming sheet names of Sheet1 and Sheet2, and the columns of data are A
through C for both sheets. And assuming your sheet1 totals begin in row 2.

=SUMPRODUCT(--(Sheet2!$A$2:$A$100=A2),--(Sheet2!$C$2:$C$100=C2),--(Sheet2!$B$2:$B$100))

I just used 100 rows, but if you need more, feel free, just ensure that all
references are the same length in rows!

Hello. I already search some post about this but I didn't understood.

I have a sheet with 3 columns: EmployeeNumber; Name; AdmissionDate

In another sheet I have another 3 columns: EmployeeNumber; NumberOfHours; Date

I need to sum in sheet one all hours that are in sheet two, but I need

So, in resume I need to sum all hours from an employee that are equal or
bigger is AdmissionDate

I have Excel 2003 and 2007, so ......

Please Help.
