How to load a scene on collision

Hi I need to know how to load a scene on collision, for example I want it so when the first person controller collides with my door object the next scene will load. Thanks

void OnCollisionEnter(Collision coll)
{
if(coll.gameObject.tag == “exit”)
Application.LoadLevel(string level name or int level);
}

If you want to use trigger instead of collision, use Collider instead of Collision like so.

void OnTriggerEnter(Collider coll)
{

}
