Respawn script not working!

So I have an enemy game object. I managed to get it spawning, which was awesome but then I added a health bar to it and it stopped spawning for some reason. I've included both the script on the enemy ("EnemyControl") and the "Respawner" script.

Enemy Script

 #pragma strict
 
 public var respawner : Respawner; // The respawner associated with this enemy
 
 private var thisTransform : Transform;
 private var anim: Animator;
 
 var smoothTime = 1; 
 var xOffset : float = 0; 
 
 
 //ENEMY HEALTH VARIABLES
 public var health:int = 100;
 public var healthPercent:float = 1;
 public var healthBlock:GameObject;
 public var healthBlockWidth:float = 1;
 public var healthBlockSize:float = 100;
 private var oHealth:int = 100;
 public var healthBlockPos:float = 1.0;
 
 
 function Start (){
 
     thisTransform = transform;
     
     //ENEMY HEALTH
     healthBlock = this.transform.Find("HealthBlock").gameObject;
     healthBlockWidth = healthBlock.transform.localScale.x;
     healthPercent = healthBlockWidth/health;
     healthBlockPos = healthBlock.transform.localPosition.x;
     oHealth = health;
     
 }
 
 
 function OnTriggerEnter2D(other : Collider2D) {
 
     if(other.gameObject.tag == "Player"){
     
     canDie = true;
     
     
     }
 }
 
 
 function OnTriggerExit2D(other : Collider2D) {
 
     if(other.gameObject.tag == "Player"){
     
     canDie = false;
     
     }
 }
 
 
 function FixedUpdate (){
 
     //kill enemy
     if(canDie && Input.GetButtonDown("Fire1")){
         
         
         health-=20; 
     }
     
     
     //ENEMY HEALTH
     healthBlockSize = health*healthPercent;
     healthBlock.transform.localScale.x = healthBlockSize;
     healthBlock.transform.localPosition.x = (((oHealth-health)*-1.0)/200)+healthBlockPos;
     if(health<=0){
         
         killEnemy();
     }
         
     
 }
 
 function LateUpdate(){
     
             //follow player code
            thisTransform.position.x = Mathf.Lerp( thisTransform.position.x, player.position.x + xOffset, Time.deltaTime * smoothTime);
  
 }
  
 
 function killEnemy(){
     
     
     respawner.SendMessage("EnemyDied", this); //Tell the respawner to kill enemy
     
     health = 100;
     
     
 }

And the Respawner script

 #pragma strict
 
 var enemyToSpawn : EnemyControl;
 
 var respawnTime : int = 3; 
 private var dead : boolean = true;
 private var deadTime : int = 0; 
 private var nextRespawn : int = 0; 
 
 private var anim: Animator;
 
 
 private function Respawn() {
     
     var enemy : GameObject = GameObject.Instantiate(enemyToSpawn.gameObject, transform.position, transform.rotation);
     enemy.GetComponent(EnemyControl).respawner = this;
     
 }
 
 
 function Update() {
     if (Time.time >= nextRespawn && dead) { 
         Respawn(); 
         dead = false; 
     }
 }
 
 function EnemyDied(theEnemy : EnemyControl) {
     
     deadTime = Time.time;
     nextRespawn = Time.time+respawnTime;
     GameObject.Destroy(theEnemy.gameObject);
     
 
 }

I have no idea what I'm doing wrong. Any help greatly appreciated. Cheers!
