ActionScript 3

Hello, I'm new to the forum and in real need for some help (been working on this forever).

Okay So I have a main Flash File, on frame 4 I have and empty MovieClip where I have loaded an external swf file. This works perfectly. I've used the following code...

import flash.display.Loader;
import flash.net.URLRequest;
import flash.display.MovieClip;
import flash.events.MouseEvent;

var swf:MovieClip;
var loader:Loader = new Loader();

var MazeGame:URLRequest = new URLRequest("swf/MazeGame.swf");

loader.load(MazeGame);

loadmaze.addChild(loader);
.


At the end of the movieclip which I have loaded externally I have a button which I want to navigate the user back onto the main timeline of the original file.

This is the code for the button currently.

race.addEventListener( MouseEvent.MOUSE_UP, raceStart );


//Function for when button is pressed.

function raceStart(e:Event):void{
frame("../") {
play();
}


Could anyone help me please the gotoandstop function isnt working for me.
Thank you all
