Looping scenes by pressing "X" button on PS3 controller

Hi there,

I am having some difficulty getting this right. And I dont get why.

I want to users to walk to a door for instance press X on the controller and then the next level must start-up. First off I have a box collider, and attached to it is attached is a tag (When I add this tag to my door, the box-collider is no more a box collider and I can walk strait through it, what am I doing wrong?) and the following script:

 #pragma strict
 
 var Level2 : String;
 
 function Update() {
 if(Input.GetKey("joystick 14th axis")){
 Application.LoadLevel ("Level2");
 }
 }
 
  function OnTriggerEnter (cubeTrigger : Collider)
  {    
      Debug.Log ("OnTriggerEnter : cubeTrigger.tag = " + cubeTrigger.tag); // shows the tag of the trigger
      // if tag is door
      if (cubeTrigger.tag == "Room")
      {
          Application.LoadLevel ("Level2"); 
      }
  }

I have also created a C# script and added it in the place of the script above and it doesnt work either:

 using UnityEngine;
 using System.Collections;
 using XInputDotNetPure;
 
 public class looptonewscenecs : MonoBehaviour {
 
     public string Level2;
     public void Update()
     {
         if (!Input.GetButton("X button"))
             return;
         Application.LoadLevel(Level2);
     }
 }
 

In the Input Manager I have assigned the "X" key of my controller to the 14th axis (Joysticks). Both of my scenes have been added to the Scenes in Build. I dont have any errors when I build the game, except I am stuck in the first level no matter what I do.

Any suggestions would be appreciated, I am stuck!
