Why it is not working? :(

I made this simple code that should give you 10 points of accuracy when you hit the target, and subtract 10 points if you miss it, but it simply doesn't work. It doesn't increase when I click on the target, but it decreases if I click elsewhere, and it seems like the function to check if the sprite was clicked is broken in general.

These are the only two events ? Seems ok. Maybe check the collision box on the objects. Try a different action like target destroy on click to determine if the clicking is working, if the destroy works then this means your variables are being adjusted and forced elsewhere.
