Subtotal - Can I use Sumproduct ?

I'm using a sheet with filtered results and have used subtotal to ensure that some averages update dynamically based on filtered results. One of the fields requires me to use =sumproduct to calculate the correct numbers for an average. The following formula works without the filters...

=SUMPRODUCT(G8:G34*H8:H34)/SUM(G8:G34)

I've adjusted it to read

=SUMPRODUCT(G8:G34*H8:H34)/SUBTOTAL(9,G8:G34)

The issue I'm faced with is getting the ranges (G8:G34 and H8:H34) to change everytime I change the filter. The list of Function Numbers for Subtotal does not include an option for sumproduct. Is there a way around this ?

I'm sorry, but I don't follow. What does XXX represent ?

Try something like

=SUMPRODUCT(--($G$8:$G$34),--($H$8:$H$34),--(SUBTOTAL(3,OFFSET($G$8,ROW($G$8:$G$34)-MIN(ROW($G$8:$G$34)),,))))/SUBTOTAL(9,$G$8:$G$34)

should only apply to visible cells

It means whatever your criteria is however it won't work, the formula I
provided will only perform the calculations on visible cells
