Im NOT Switching Scenes!! PLEASE HELP!!

So Im trying to make it so that once my character hits the door, it`ll act as a portal and take him to the next scene but its not working. Ive tried OnTriggerEnter and OnCollisionEnter. This is mycurrent code.

function OnControllerColliderHit(other : Collision)
{
	if(other.gameObject.name == "Portal1"){
	Debug.Log("You are in the Portal");	
	Application.LoadLevel("MainMenu");
	
	}
}

You mentioned below that you have Colliders on. Do you also have RigidBody on them and at least one set as a Trigger?
