Narrowing down value list based on values in adjacent column

Hi all,

Have a list of SKU's that I am trying to narrow down.

Column A has the sku's I would like to narrow down, column F has all the sku's in column A plus more.. Column G has the quantities of the sku in column F.

So for Column A, I would weed down what SKU has a zero quantity (or blank), column B should show all SKU that has a value of 1 or greater.

Please see attached.

perhaps something like this?

Yes, but I think it is returning values (SKU's) that are not in column A

If the SKU is not in column A, then I can't have it in column B.

Only trying to find what SKU (column A) have a quantity greater than 0, these values are in column F and G.
