exportRoot How to use it so javascript works on all frames

Hi. I have all my javascript on one frame.

I want it to be accessible on any frame ie: so I don't have o copy and paste the same code a hundred times.

I know I have to use exportRoot but I'm not too sure where to put it.

ie: on every variable and every function.

This is some of my code for example.

this.stop();

createjs.Touch.enable(stage);

///////////////////////////////////////////////////////////////////
//Play music

var musicHandler = playMusic.bind(this);
this.btn_playMusic.addEventListener("click", musicHandler);

function playMusic() {
	var bgMusic;
	bgMusic = createjs.Sound.play("bgMusic"); //in library probably.
	bgMusic.play();
	this.btn_playMusic.removeEventListener("click", musicHandler);
}
///////////////////////////////////////////////////////////////////
// drag code

var roundItems = [this.ducky, this.doggy, this.froggy, this.helicopter,  this.monkey, this.sunny, this.tania, this.flower];

for(var i = 0; i<roundItems.length; i++){	
	roundItems[i].on("mousedown", onMouseDown.bind(this));
	roundItems[i].on("pressmove", onMouseMove.bind(this));
	roundItems[i].on("pressup", onMouseUp.bind(this));
	roundItems[i].originX = roundItems[i].x;
	roundItems[i].originY = roundItems[i].y;
}
///////////////////////////////////////////////////////////////////

var nextHandler = nextFunction.bind(this);
this.btn.addEventListener("click", nextHandler);

function nextFunction() {
	this.btn.removeEventListener("click", nextHandler);
	this.gotoAndPlay("ducky");
}
