Mouse Trail Help!

[AndyChickenGame]

Hey guys,

so I'm working on a game with a good buddy of mine and i came across
a little trouble. My friend wants it so the mouse has a trail once you
move the mouse along the screen. I found a tutorial online and it worked
out great. But the problem is that the movieclips that i already had
won't work well with the cursor. I've attempted to find something about
mouseEnabled but I do not know how to apply it correctly. Any ideas?

[Edit: It would really help if someone replied!!!!!]

Here's the code. Thanks

var centerX:Number = stage.stageWidth / 2;
var centerY:Number = stage.stageHeight / 2;

ball.addEventListener(Event.ENTER_FRAME, moveBall);

var timer:Timer = new Timer(100,400000);
timer.addEventListener(TimerEvent.TIMER, createTrailBall);
timer.start();

function moveBall(e:Event):void {

	var xpos:Number = mouseX;
	var ypos:Number = mouseY;

	//Move the ball to da new coordinates
	ball.x = xpos;
	ball.y = ypos;

	angle += speed;

}
function createTrailBall(e:Event):void {

	var trailBall:Ball=new Ball();

	trailBall.x = ball.x;
	trailBall.y = ball.y;

	trailBall.addEventListener(Event.ENTER_FRAME,animateTrailBall);

	addChildAt(trailBall,10);
}
function animateTrailBall(e:Event):void {
	
	e.target.alpha -= 0.04;
	e.target.scaleY -= 0.04;
	e.target.scaleX -= 0.04;

	if (e.target.alpha < 0) {
		e.target.removeEventListener(Event.ENTER_FRAME,animateTrailBall);
		removeChild((MovieClip)(e.target));
	}
}
