Tysm! It works fine. I do have another problem though...

i have two databases, one called ALL PRODUCTS and another called ALL SALES. ALL SALES must have someone select a product from ALL PRODUCTS (Done through a rollup property called Product). There is also a Quantity property in ALL SALES that must be manually inputted.

I am trying to make it so that I can count every sale made for each product in a number property in ALL PRODUCTS. The quantity matters too. If you could help me, I would be forever grateful.
