controlling external swf file timeline

Hi everybody

I have a simple question but I can't solve that my self and appreciate any help.

I have two frames:

1: two buttons to load different swf files in the second frame

2: the second frame in which the swf files are loaded. and of course there is a button to go back frame 1; and some buttons to control swf timeline;

so they're loaded in the second frame very well, and using the back button I can go back frame 1 as well,  but in the second frame I have some buttons to control the loaded swf, and have certain functions for them, but the buttons don't work

here is my code in frame 1:

import flash.events.MouseEvent;

import flash.display.Loader;

import flash.net.URLRequest;

stop();

var myLoader: Loader = new Loader();

load_btn.addEventListener(MouseEvent.CLICK, myLoad);

function myLoad(evt: MouseEvent): void

{

                gotoAndStop("loadingPage");

                myLoader.load(new URLRequest("test-movie.swf"));

                loader.addChild(myLoader);

}

load_btn2.addEventListener(MouseEvent.CLICK, myLoad2);

function myLoad2(evt: MouseEvent): void

{

                gotoAndStop("loadingPage");

                myLoader.load(new URLRequest("test-movie2.swf"));

                loader.addChild(myLoader);

}

and here is my code in frame 2:

import flash.events.MouseEvent;

import flash.events.Event;

addEventListener(Event.ENTER_FRAME, swfLoaded);

var currentSWF:MovieClip = MovieClip(loader.content);

function swfLoaded(evt:Event):void

{

function button_forward(e:Event):void{

                 currentSWF.nextFrame();

                  }

function button_rewind(e:Event):void{

                 currentSWF.prevFrame();

                  }

function button_pause(e:Event):void{

                 currentSWF.stop();

                  }

function button_play(e:Event):void{

                 currentSWF.play();

                  }

  }

back_btn.addEventListener(MouseEvent.CLICK, goHome);

function goHome(evt:MouseEvent):void

{

                removeChild(loader);

                gotoAndStop("home");

}

and there is no errors or warnings, etc. it just doesn't work

I can't find  out where my problem is.

Thanks for your help
