I'm trying to play a certain animation when a button is pressed, but it isn't working.

(This is the project)

I'm trying to play the animation, axing, but it won't work, I don't know if it's because another animation is trying to play or something else, I would just like to know to get the animation to play.

Link is broken and what you're saying is probably true as this is a common error. You can make sure multiple animation conditions are not true, such as if you want to play an idle animation you could say player is not moving, AND not jumping, so a jump animation and a walk animation would still play correctly.
