How to access a second script on same object

I have a script that teleports an object that collides with an object tagged TeleportIn

    var target : Transform;
     
     var pathScript : Enemy_GroundUnit;
  
  function Awake() 
     {
     //connect to outbound teleporter
     target = GameObject.FindWithTag("TeleportOut").GetComponent(Transform);
     }    
      
     function Update () 
     {    
     }       
      
     function OnTriggerEnter (col : Collider) 
     {    
     //need TeleportIn tag on TeleportIn Object
     if(col.gameObject.tag == "TeleportIn") 
     {        
         this.transform.position = target.position;
         pathScript.GetNewPath();         
     }
 }

I am getting a NullReferenceException from the bottom line

 pathScript.GetNewPath();

The script Enemy_GroundUnit is attatched to the same object and has a function called GetNewPath. I want to call it after the object telports. Am I calling it wrong or is this something wrong with that script?
