Collision To Next Level Is Not Working

#pragma strict
function OnCollisionEnter(collision: Collision) {
if (collision.gameObject.tag == “Exit”){
Application.LoadLevel (“Level_2”);
}
}

the idea of this code is to have my player hit the cube(which is tagged “Exit”), and then the game will switch to another level called Level_2

The problem is the collision just doesn’t work. My script is attached to my player which is the standard first person controller.

The cube has a box collider on it so that isn’t an issue. I couldn’t use the first script because I got this error “Tag is not a member of UnityEngine.Collision”
The second script had no effect. I’m attaching my scene so you can see for yourself.
