If the combination of criteria are unique:

=SUMPRODUCT(--(Sheet1!A$1:A$10=A1),--(Sheet1!B$1:B$10=B1),Sheet1!C$1:C$10)

Hi,

I have 2 worksheets in a workbook:

Sheet1:

Column A B C
row1 W X 3
row2 Y Z 4

Sheet2:
Column A B C
row1 Y Z

The value of cell C1 should be 4, according to sheet1
If I want to use vlookup function to retrieve the value from Sheet1, is it
possible to do so? Since I am searching on more than 1 column......

Can anyone help? Thanks in advance.
