builtins.UnboundLocalError: local variable 'currentWalk' referenced before assignment. This is what happens when I run the code. I am trying to animate walkLeft2 and walkRight2 but it is not working, walkLeft and walkRight are animating. This is because the walkcount was originally eliminated if it was above 12 but I changed it to an if statement and now it does not run.
