I'm totally lack of experience, this is easy for you guys, if someone can help me i need to deliever this report to my boss.

Cell I27=SUMPRODUCT((MOD(ROW(I10:I25);3)=1)*(I10:I25))

Cells I10 contains a formula =SUM(D10:H10) and so on...

so the result of cell I27 is #VALUE! because it reads the formula (=SUM(D10:H10) instead of the result of that formula

What do i need to do?!
