Multiplayer Walk animation playing for opposite person

Hey everyone! I'm not very new to Unity, but this is the first time I've made a successful multiplayer game. When I walk in multiplayer, it shows the other player walking, and the other player doesn't see the animation. I think this has something to do with global and local stuff (I want the animation to be visible for both players though). Does anyone know how to fix this? Here is the animation script I'm using.

 function Update() {
     var v = Input.GetAxis("Vertical");
     if(Mathf.Abs(v) > 0.1f) {
         animation.CrossFade("Walk");
     }
     else animation.CrossFade("Idle");
 }
