I want to rotate the model to face player, not bend?

I posted this question about 7 hours ago but included the wrong code, for some reason the post won't edit so I'm posting again. I basically want my enemy model to always face the player but not bend when the player is close.

EDIT: Sorry, what I'm trying to get is I only want the model to rotate left/right, not up and down. The model will rotate so it's facing the sky if I get close, I just want the model to turn around, not bend backwards/forwards.

 var PlayerHealth = 10;    //PlayerHealth Value
 var TakeDamage : boolean; //Damage toggle
 var target : Transform; //the enemy's target
 var moveSpeed = 3; //move speed
 var rotationSpeed = 3; //speed of turning
 var myTransform : Transform; //current transform data of this enemy
 
 function Awake()
 {
     myTransform = transform; //cache transform data for easy access/preformance
 }
 
 //When the player and AI meet enable Damage Toggle
 function OnTriggerEnter(other : Collider){
     if(other.tag == "Player"){
         TakeDamage = true;
     }
 }
 
 //When the player and AI seperate disable Damage Toggle
 function OnTriggerExit(other : Collider){
     if(other.tag == "Player"){
         TakeDamage = false;
     }
 }
 
 function Start()
 {
      target = GameObject.FindWithTag("Player").transform; //Target the player
 }
 
 function Update () {
     //Rotate to look at the player
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
     
     //Move towards the player
     //myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
 
 }
