Animation and Stop Moving Won't Work?

Hi, I'm making a 2D infinite runner, and I am having trouble with this script.

 using UnityEngine;
 using System.Collections;
 using System;
 
 namespace UnityStandardAssets._2D
 {
     public class PlatformerCharacter2D : MonoBehaviour
     {
         bool CanMove = true;
         bool MoveWait=false;
 
         void OnCollissionEnter2D(Collision col1){
             if (col1.gameObject.tag == "Enemy") {
                 GetComponent<Animation> ().Play ("RedGiantDeathToAll");
                 CanMove = false;
                 if (!MoveWait)
                     StartCoroutine (MoveToWait ());
             }
         }
 
         public IEnumerator MoveToWait(){
             MoveWait=true;
             yield return new WaitForSeconds(1.5f); //Change to Animation Duration
             MoveWait=false;
             CanMove=true;
         }
     }
 }

There are no errors. But it won't work. When I run the game, the animation won't play. I have 2D box colliders on all enemies and the player. I have a tag called "Enemy" and I put it on all the enemies. The tag for the enemy is the same. I have colliders on both gameObjects, and there are 2D Rigidbody's on both, too. There is no spelling errors. Turns out the death animation was named, "Die", not "RedGiantDeathToAll". It used to be named that.

Please help! I'd be grateful!!
