Restart Button

I'm very new to flash and i'm on chapter 7 on actionscript classroom in a book. I have an assignment in that book were i'm supposed to add a restart button to this game that drops fruit off a tree and the user catches it in a basket. I'm not sure if we are allowed to post our code here or not so jump me to bad. There are 15 frames in this project. Not getting a error when i click the restart button, but it is not restarting the program.

var fruitArray:Array = new Array(Apple,Strawberry,Pear,Banana,

Orange);

var fruitsOnstage:Array = new Array();

var fruitsCollected:int = 0;

var fruitsLost:int = 0;

for (var i:int = 0; i<20; i++) {

var pickFruit = fruitArray[int(Math.random() * fruitArray.

length)];

var fruit:MovieClip = new pickFruit();

addChild(fruit);

fruit.x = Math.random() * stage.stageWidth;

fruit.y = Math.random() * -500;

fruit.speed = Math.random() * 15 + 5;

fruitsOnstage.push(fruit);

}

basket_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragBasket);

stage.addEventListener(MouseEvent.MOUSE_UP, dragStop);

function dragBasket(e:Event):void {

basket_mc.startDrag();

}

function dragStop(e:Event):void {

basket_mc.stopDrag();

}

stage.addEventListener(Event.ENTER_FRAME, catchFruit);

function catchFruit(e:Event):void {

for (var i:int = fruitsOnstage.length-1; i > -1; i--) {

var currentFruit:MovieClip = fruitsOnstage;

currentFruit.y += currentFruit.speed;

if (currentFruit.y > stage.stageHeight - currentFruit.

height) {

currentFruit.y = 0 - currentFruit.height;

fruitsLost++;

field2_txt.text = "Total Fruit Lost: " + fruitsLost;

}

if (currentFruit.hitTestObject(basket_mc)) {

fruitsCollected++;

removeChild(currentFruit);

fruitsOnstage.splice(i,1);

field1_txt.text = "Total Fruit Collected: " +

fruitsCollected;

if (fruitsCollected >= 20) {

basket_mc.gotoAndStop(20);

} else if (fruitsCollected > 15) {

basket_mc.gotoAndStop(15);

} else if (fruitsCollected > 10) {

basket_mc.gotoAndStop(10);

} else if (fruitsCollected > 5) {

basket_mc.gotoAndStop(5);

}

}

}

if (fruitsOnstage.length <= 0) {

field1_txt.text = "You Win! You have collected enough fruit for dinner.";

field2_txt.text = "";

stage.removeEventListener(Event.ENTER_FRAME, catchFruit);

}

if (fruitsLost >= 20) {

field1_txt.text = "Sorry, you lose. You have lost too much fruit!";

field2_txt.text = "";

stage.removeEventListener(Event.ENTER_FRAME, catchFruit);

for (var j:int = fruitsOnstage.length-1; j > -1; j--) {

currentFruit = fruitsOnstage;

removeChild(currentFruit);

fruitsOnstage.splice(j,1);

}

}

//Restart button

aButton.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

function fl_ClickToGoToAndStopAtFrame(event:MouseEvent):void

{

  stage.addEventListener(Event.ENTER_FRAME, catchFruit);

  gotoAndStop(1);

}
