I am attempting to create a worksheet formula as follows:

Cell A3 is to reflect the PRODUCT of Cells A1:A3 on Worksheet2.
Cell A4 is to reflect the PRODUCT of Cells A4:A6 on Worksheet2.
Cell A5 is to reflect the PRODUCT of Cells A7:A9 on Worksheet2, and so on.

Unfortunately, when I copy the formula from Cell A3 to A4, I'm not using the
OFFSET function properly. Any suggestions?
