Why is my animation not working?

Why is my animation not working? I always get stuck in my down and left animations. As well when I let off of the pressed key the animation continues. I have the Boolean, and the code.

What is the difference between “WalkLeft” and “Left” ?
If I am guessing it correct then you should replace your “Left”,“Right”,“Up” and “Down” in Update function with “WalkLeft”, “WalkRight”, “WalkUp” and “WalkDown” respectively.
