Scratch

Hello there, I am a 6th Form student in desperate need for some assistance with an issues I have ran into.

Problem: When bullets = 0, targets hit still registers points - Basically, my game is a target practise game where you shoot an M4 rifle at the targets that pop up. Now after so much time being put into the game, I cannot seem to fix a very simple issue. When there are no bullets left in the clip, when clicked on the target, it still registers it as a point; I have tried many different if statements, changing variables etc etc.

Please any help would be greatly appreciated.
