Good Day to all!
Is there any possibility to use the SUMPRODUCT function along with AutoFilter?
I have the following situation:

Column A: Commodities
Column B: Origin
Column C: Weight
Column D: Quantity

On cell E1, I need a function to give me the average weight of the commodities, based on a selection with the AutoFilter.
For example, in other words:

If I select "France" in column B using the AutoFilter, I'd like a function to give me the average weight of all the commodies, i.e, multiplying the quantities by the weight and dividing by the total quantity.
It's more or less SUBTOTAL with SUMPRODUCT

Any chance to do it?

Thanks a lot,
Gustavo.
