Damaging Enemies

Hi, I'm trying to make an enemy in my game, I got the health losing part right, but I can't seem to get the enemy to be killed. I made a single body enemy that is a trigger so I can walk right through it, but it's also that so it can hurt me and stop moving.

  var timer = 20;
 var forward = false;
 var backward = false;
 var stop = false;
 var timer2 = 0;
 var stop2 = false;
 
 private var inputMoveDirection : Vector2 = Vector2.zero;
 public static var moveDirection : Vector2 = Vector2.zero;
 //by the way, make sure to only use functions when they work
 function OnTriggerEnter(){
 stop = true;
 }
 function OnTriggerExit(){
 stop2 = true;
 }
 
 
 function Update () {
 var controller : CharacterController = GetComponent(CharacterController);
 //components needed
 moveDirection = transform.TransformDirection(moveDirection);
 //Movement
 if(stop == false){
 if (timer == 20){
 forward = true;
 backward = false;
 }
 if (timer == -20){
 forward = false;
 backward = true;
 }
 if(forward == true){
 moveDirection = Vector2(10, 0);
 timer--;
 }
 if(backward == true){
 moveDirection = Vector2(-10, 0);
 timer++;
 }
 }
 if(stop == true){
 moveDirection = Vector2(0, 0);
 }
 
 if (stop2 == true){
 timer2++;
 if(timer2 == 40){
 stop = false;
 stop2 = false;
 timer2 = 0;
 }
 }
 
 //force movement into seconds instead of frames
 controller.Move(moveDirection * Time.deltaTime);
 }
 
 function can_die() {
 Destroy(gameObject, 0.0);
 
 }

The CharacterController is off in the "I'm not in the game" part. I have tried to make a script to conquer this beast of a script:

   var damage = 2;
  var iamthedamage : boolean = false;
 
 function OnTriggerEnter() {
     if (Move9.attackready == true){
     SendMessage("can_die", damage, SendMessageOptions.DontRequireReceiver);
     iamthedamage = true;
     }
     else {
     iamthedamage = false;
     }
 }

I'm unsure of what the problem is but help would be appreciated.
