How to access a second script on same object

Questions & Answers
1

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?

to reference the script do this

gameObject.GetComponent(Enemy_GroundUnit).GetNewPath();
