Why won't my game over scene load in the build?

Ive created a game over screen, but whenever the lives reach 0 the game continues to play.

var Life = 3;

function Loselife()
	Life --;

function OnGUI () {
	// Make a background box
	GUI.Box (Rect (10,10,100,25), "Life: "+Life);

function update()
if(Life == 0){Application.LoadLevel ("Lose");

My script to call the LoseLife function works properly as The number of lives decrease correctly, but when it reaches 0 it doesnt move to the Lose scene.

Here is the other script:

var Life : Life;

function OnCollisionEnter(collision : Collision){

iTween.FadeTo(gameObject,{"alpha":0, "onComplete":"destroy"});
GetComponent(CapsuleCollider).enabled = false;

	function destroy():void{



1: function Update() (needs to be capitalized)

2: If it still won’t work, make sure the scene has been added in build settings, and that the name matches… or you can change to the scene number to be sure, as in:
