Walking/Movment Animation not Working

So I am extremely new to Unity, so I don't know much, but when I want to make a animation for my first person character, it won't enable the animation. I dragged the java script file to the hands of the first person character, but it does not work. I have a simple walking animation. The name of the animation is walkinganimation , here is the script.

 

The hands object must have an Animation component, and the list of animations on that component must include "walkinganimation".
