How to make Google Sheets display the price separately for each drop-down list in a cell?

Question

Google Sheets

So I want to add another item for performers, and so that the green cell displays its own amount for each when choosing

Answer 1

I hope I understood you correctly

=SUMIF(E:E;J1;I:I)

• E:E- what we check
  
• J1- what we check for, condition
  
• I:I- what we sum up
  

Answer 2

Good afternoon! Another question arose.
Previously, when you clicked the checkmark, the price was displayed.
Now I also wanted to do the same, what should I add for this?

This is the formula now
. When adding also (B:B;TRUE;), an error occurs
