Hi guys, my issue is just a simple one, I’m trying to use onTriggerEnter to go to a game over screen should the ball fall from the board in my tilt game, I’m using a large invisible cube underneath the board for this, not sure if that’s where I’m going wrong? Here is my current code anyway, any help is appreciated 
using UnityEngine;
using System.Collections;
public class GameOver : MonoBehaviour {
public void onTriggerEnter (Collider collider)
{
if (collider.gameObject.tag == "Player")
Application.LoadLevel (6);
}
}
