[Solved] Help with Triggering

[StarKeeper]

I wanted to have my shop prices based on a variable. I found this impossible, so what I wanted to do was make it so whenever a unit buys an item from a shop, it charges them extra based on that variable.

I can't find a generic unit event which will handle a unit buying an item, but I can find one which is for when they sell an item.

Please help me :/

I think I solved the issue, I did it so when the shop sells an item not when a unit buys one
