problem extracting transform from an array

hi all, this is a script to move an object in V3 towards a target object, the target object is randomly chosen from an array of object with a certain tag, the main issue is in my find target function but im lost, any help would be appreciated

 #pragma strict
 
 
 var moveSpeed = 3; //move speed
 var rotationSpeed = 3; //speed of turning
 //var tower: GameObject;
 var myTransform : Transform; //current transform data of this enemy
 var targets : GameObject[] ;//hold an array of target objects
 var target : Transform; //the enemy's target
 
 function Awake()
 {
     myTransform = transform; //cache transform data for easy access/preformance
 }
  
  
 function Start()
 {//find all the game objects tagged as target
      targets = GameObject.FindGameObjectsWithTag("target"); 
     //if no target set run function find target
     if(target==null){
     findTarget();
 }
 }
 
 function Update () {
     //rotate to look at the player
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.transform.position - myTransform.position), rotationSpeed*Time.deltaTime);
  
     
     //move towards the player
     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
  
 }
 
 
 function findTarget(){
 //randomly pick a target from the collected array
     var newTarget : int = Random.Range( 0, targets.length );
 
 //set the chosen randomly picked target as the curren target
 target = targets[newTarget].transform.position;
 }
