Playing Different Animation Troubles

I want my code to have my gameobject (Goblin) to stand animation when player is far away, then when player is close to chase and use the walk animation. Then when player is super close to play the attack01 animation, Finally I want the enemy to die when its hitpoints = 0 and play dead animation.

My problem is the attack01 animation doesnt stop playing and the dead animation wont start.

Here is my code; any help would be appreciated

 #pragma strict
 var maxHealth = 10;
 static var EXPgive = 50;
 static var _isdead = false;
 
 var IgnoreDistance = 12.0f;
 var AttackDistance = 4.0f;
 var rotationSpeed = 1.2f;
 var moveSpeed = 1.2;
 var target : Transform;
 var myTransform : Transform;
 
 
 function Awake () {
 myTransform = transform;
 maxHealth = 10;
 EXPgive = 50;
 target = GameObject.FindWithTag("Player").transform;
 }
 
 function Update () {
 myTransform.position.y = 0.4;
 var distance = Vector3.Distance(myTransform.position, target.position);
 
 if (distance >= IgnoreDistance){
 WaitforPlayer();
 }
 if (distance <= IgnoreDistance){
 lookforPlayer();
 }
 if (distance <= IgnoreDistance){
 if (distance >= AttackDistance){
 moveAtPlayer();
 }
 }
 }
 function moveAtPlayer(){
     transform.LookAt(target);
     animation.CrossFade("walk");
     transform.position += transform.forward*moveSpeed*Time.deltaTime;
     }
 function WaitforPlayer(){
     animation.CrossFade("stand");
    }
 function lookforPlayer(){
     animation.CrossFade("stand");
     transform.LookAt(target);
    }
   function ApplyDamage(damage : float){
     if(maxHealth <= 0.0){
     return;
     
  }
     maxHealth -= damage;
     _isdead = true;
     animation.CrossFade("damage");
     transform.LookAt(target);
     if(maxHealth <= 0.0){
     Die();
     }
  }
 
 function Die(){
 Player.enemydied = true;
 Player.curEXP+=50;
 Debug.Log("stop animation here");
 animation.Stop("attack01");
 animation.CrossFade("dead");
 yield WaitForSeconds(2);
 Destroy(this.gameObject);
 Player.enemydied = false;
 }
 
  function OnTriggerStay (other : Collider) {
  if(other.transform.tag == "Player"){
  animation.CrossFade("attack01");
  Debug.Log("E took a swing");
  }
  }
   function OnTriggerExit (other : Collider){
      if(other.gameObject.tag == "Player") {
         Debug.Log("E Left");
      }
  }
