UnboundLocalError: local variable 'x' referenced before assignment
This is the error im getting. I want to run the x and y coordinates through to circle and square then run them into windowevents through the if statement but doesnt seem to work. I'm not sure whats wrong...Please help me.
Ps: x and y are both numbers just fyi.
