Dynamic table calculations

I am attempting to create a dynamic table that will execute formulas based on a selection from a drop-down menu.

I have created a test spreadsheet to support my request, which can be found here⬅️⭐️

In the upper table, I input values, while the bottom table performs calculations.

My goal is to have the calculations apply to the range selected from the upper table whenever I change the value in the drop-down menu in the bottom table (B37:B61).

In the sandbox tab, the bottom table contains formulas for the first item in the list. These formulas should update when I select a different item from the list, and they are based on the corresponding range in the upper table.

Thank you!
