move to next scene

Help!!! Im a newbie in unity and javascript.

I want my character move to next scene after it hits the given distance(fixdist).

Here's my code:

var targetObject : Transform;

 function Start(){
 
     targetObject = GameObject.Find("First Person Controller").transform;
 }
 
 function Update(){
 
     var fixdist : float = "179.3872";
 
     if (targetObject!= null){
         
         var dist : float = Vector3.Distance(targetObject.position, this.transform.position);
         
         print ("Distance to target Object: " + dist);
         
         if (targetObject)
             Application.LoadLevel(1);
