How to drag from pivot table

Hello, I have a problem dragging from the pivot table

basically, I want to get quantity*price (Yellow area in my file). I get the price from another sheet and quantity from pivot table but when i try to drag data, it doesnot work. The problem is the data from pivot table(quantity) does not go as I expect. what should I do?
I attached my file in this post
Thank you very much

Instead of clicking into your pivot when you select the value you want to multiply, try typing the exact cell reference, i.e.: A4*F4

Thank you very much. It's so easy but I did not expect that at all.
