Help with a complicated IF function

Hello,

I wnoder if anyone can help me with the following formula.

In human language terms I want the formula to do the following:

If the cell A9 in sheet 1 is the same as the cell I9 in sheet 2, and when the values in column B sheet 1 equal the same as the values in column E sheet 2 then put all the values that have that criteria from column G on sheet 2 onto column R in sheet 1. All of this only when the values in the column G on sheet 2 are bigger than 0.

Does that make sense?

Thank you for any help.
