Waypoint pathfinding gone terribly wrong.

Hey everyone, i have this script(Below). And its my messy attempt at doing a waypoint pathfinding script without arrays, the problem is, when the enemy gets to the first waypoint, he turns upways, angled himself, and flies away.

 var Waypoint1 : GameObject;
 var Waypoint2 : GameObject;
 var Waypoint3 : GameObject;
 var Waypoint4 : GameObject;
 var Waypoint5 : GameObject;
 var Waypoint6 : GameObject;
 var TargetWaypoint : GameObject;
 
 var Counter : int = 1;
 
 
 
 
 function Start () {
     Waypoint1 = GameObject.Find("Waypoint1");
     Waypoint2 = GameObject.Find("Waypoint2");
     Waypoint3 = GameObject.Find("Waypoint3");
     Waypoint4 = GameObject.Find("Waypoint4");
     Waypoint5 = GameObject.Find("Waypoint5");
     Waypoint6 = GameObject.Find("Waypoint6");
     TargetWaypoint = GameObject.Find("Waypoint" + Counter);
 }
 
 function Update () {
     
     var toTarget : Vector3 = TargetWaypoint.transform.position - transform.position;
     
  
     var turnRate : float = 200 * Time.deltaTime;
     var lookRotation : Quaternion = Quaternion.LookRotation(toTarget);
     transform.rotation = Quaternion.RotateTowards(transform.rotation, lookRotation, turnRate);
     
     transform.Translate(Vector3.forward * Time.deltaTime);
     
 }
 
 
 function OnCollisionEnter( hit : Collision)
 {
     if (hit.gameObject.name == GameObject.Find("Waypoint" + Counter))
     {
         Counter = Counter + 1;
         Debug.Log("We collided");
         
         TargetWaypoint = GameObject.Find("Waypoint" + Counter);
     }
 
 
 
 
 }

I noticed that this code: if (hit.gameObject.name == GameObject.Find("Waypoint" + Counter)) { Counter = Counter + 1; Debug.Log("We collided");

         TargetWaypoint = GameObject.Find("Waypoint" + Counter);
     }

is not executing for some reason. so i figure thats the problem. but i dont know why its not working.

Any help would be nice.
