How would I play a sound in a certain range of an object?

I am not sure what I have done wrong in this script I have created, I used my knowledge of java to put this together, but not sure why this is not working. taking a guess, maybe I have done it in a wrong layout?

 var theplayer : GameObject;
 var speed : float;
 var range : int;
 
 public var close : AudioClip;
 public var aware : AudioClip;
 public var retreat : AudioClip;
 
 function Update (){
 
 range=Vector3.Distance(theplay.transform.position,transform.position);
 {
 if (range<40){
       transform.LookAt(theplay.transform.position);
       AudioSource.PlayClipAtPoint(aware, transform.position);
 }
 }
 {
 range=Vector3.Distance(theplay.transform.position,transform.position);
 if (range<20){
       AudioSource.PlayClipAtPoint(close, transform.position);
 }
 }
 {
 range=Vector3.Distance(theplay.transform.position,transform.position);
 if (range<12){
       transform.Translate(-Vector3.forward*speed);
       AudioSource.PlayClipAtPoint(retreat, transform.position);
 }
 }
 }
