Animation play when player collides/hits an GameObject

So basically I've been doing many researches on Unity Answers for the following topic, I couldn't really find one at all. I've managed to find a script that changes scenes once you collide with an object, but now I've been spending hours editing my script, I can't get it to work. There's a short time-out before you change scenes, it takes 3 seconds once you've touched the object in order to swap scenes.

So far, here's the script of the "scene swap":

 private var NL = false;
 
 function OnControllerColliderHit(hit:ControllerColliderHit) {
 if(hit.gameObject.tag == "OnTouch Reset")
 {
 Debug.Log( hit.gameObject.tag );
 yield WaitForSeconds (3);
 NL = true; } }
 
 function LateUpdate() { if(NL) {
 Application.LoadLevel(1);
 NL=false;
 }
 
 }

It could be just a easy change, but I'm obviously lost with the script.

Any help is truly appreciated.
