New Game & Quit Game in 1 script

Hi guys,
I am working on my Main Menu for my game, And I am making a script to Start a new game and quit game. But instead of making 2 script I have decided to put it all in one.

var newGame : boolean;

function OnMouseUp(){
 if(newGame)
 newGame=true;
 Application.LoadLevel("Level_1_Awake");
 }else{
 Application.Quit();
 
}

I have not done this before thus I can’t get it to work.
I want it to be a “Boolean” which I believe would make it easier, So if I tick a box then the game would know whether to Quit the application or Load level 1.

sorry about the script being messy.
Thank you in advance!

This should work as long as you have a collider on the object:

var newGame : boolean;

function OnMouseUp () {
 if (newGame) {
     Application.LoadLevel("Level_1_Awake");
 } else {
     Application.Quit();
}
