Going to another frame after all items are in place

Question

Hello All!
I'm making some simple drag'n'drop games and am using this code to make it work:
package
    import flash.display.Sprite;
    import flash.events.MouseEvent;
    public class Main extends Sprite
        var xPos:int;
        var yPos:int;
        public function Main():void
            addListeners(s1, s2, s3, i1, i2, i3, n1, n2, n3, p1, p2, p3, b1, b2, b3, f1, f2, f3);
        private function getPosition(target:Object):void
            xPos = target.x;
            yPos = target.y;
        private function dragObject(e:MouseEvent):void
            getPosition(e.target);
            e.target.startDrag(true);
        private function stopDragObject(e:MouseEvent):void
            if (e.target.hitTestObject(getChildByName(e.target.name + "Target")))
                e.target.x = getChildByName(e.target.name + "Target").x;
                e.target.y = getChildByName(e.target.name + "Target").y;
            else
                e.target.x = xPos;
                e.target.y = yPos;
            e.target.stopDrag();
        private function addListeners(... objects):void
            for (var i:int = 0; i < objects.length; i++)
                objects[i].addEventListener(MouseEvent.MOUSE_DOWN, dragObject);
                objects[i].addEventListener(MouseEvent.MOUSE_UP, stopDragObject);
s1, s2, s3, i1, i2, i3, n1, n2, n3, p1, p2, p3, b1, b2, b3, f1, f2, f3 are objects that need to be placed correctly to win. So when they are placed correctly, what do I do to make the game recognize that the player did everything right? I'd like the game to be able to take it to another frame where a "win" graphic can be seen.
Any suggestions?

Ok people, my code looks like this now, there are no compiler errors, but how can this help me go to the next frame? Sorry for noobing you, been working with AS2 before, but this is my first assignment in AS3. A good way to learn something is by being pressured by deadlines
package
    import flash.display.Sprite;
    import flash.events.MouseEvent;
    public class Puzzle extends Sprite
        private var xPos:int;
        private var yPos:int;
        private var correctCount:int = 0;
        public function Puzzle():void
            addListeners(p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12);
        private function getPosition(target:Object):void
            xPos = target.x;
            yPos = target.y;
        private function dragObject(e:MouseEvent):void
            getPosition(e.target);
            e.target.startDrag(true);
        private function stopDragObject(e:MouseEvent):void
            if (e.target.hitTestObject(getChildByName(e.target.name + "Target")))
                e.target.x = getChildByName(e.target.name + "Target").x;
                e.target.y = getChildByName(e.target.name + "Target").y;
                //deactivate object
                e.currentTarget.removeEventListener(MouseEvent.MOUSE_DOWN, dragObject);
                e.currentTarget.removeEventListener(MouseEvent.MOUSE_DOWN, stopDragObject);
                //increment correct count
                correctCount++;
            else
                e.target.x = xPos;
                e.target.y = yPos;
            e.target.stopDrag();
        private function addListeners(... objects):void
            for (var i:int = 0; i < objects.length; i++)
                objects[i].addEventListener(MouseEvent.MOUSE_DOWN, dragObject);
                objects[i].addEventListener(MouseEvent.MOUSE_UP, stopDragObject);
p.s.: just so you know, it's a non profit thing, some games for my child's kindergarten - they are trying to introduce kids to PCs..
