Dashboard with Parameter in filtered query

I want to make what I thought would be a simple dashboard that displays parts at the top and the partnum is published. Below, I want to display the BOM for the selected partnum. But I also want a parameter for quantity which I will multiply by the quantity per from the BOM. But I can’t have a parameter in the bottom query or I get errors and Epicor said, "No you cannot have a parameter in the bottom query.

Any ideas?
