AS3 - conect Parte I, II, III, etc... to index. (problems in audio flv file)

[COLOR=#3F4549][FONT=Helvetica Neue]Good day.

I have 7 files in fla (AS3) of which 6 of them (Part I, II …) are subordinate to 1, the index.

It turns out that not always the subordinate files appear to occupy the entire length of the initial stage (index.swf)! For Part I and Part II wont work but for the other appears only half the stage!

If I click on index.swf in Part II: develops Part II … but if half of this animation I decide to go to Part III, Part III goes on stage … but the audio of Part II still ON (audio from flv file)![/FONT][/COLOR]

The code in index file:

stop ();

/Imports for page tween/

import fl.transitions.Tween;

import fl.transitions.easing.*;

/Position, declare and add tween to the loader/

var Xpos:Number = 0;

var Ypos:Number = -20;

var swf:MovieClip;

var myLoader:Loader = new Loader();

var myTween:Tween = new Tween(myLoader, “x”, Bounce.easeOut, 500, 0, 1, true);

/The default page when the website first loads/

var defaultSwf:URLRequest = new URLRequest(“parte1.swf”);

myLoader.load(defaultSwf);

myLoader.x = Xpos;

myLoader.y = Ypos;

addChild(myLoader);

/Buttons function - loads each page and adds the ‘bounce’ tween/

function btnClick(event:MouseEvent):void {

removeChild(myLoader);

var newSWFRequest:URLRequest = new URLRequest(event.target.name + “.swf”);

myLoader.load(newSWFRequest);

myLoader.x = Xpos; myLoader.y = Ypos;

addChild(myLoader);

var myTween:Tween = new Tween(myLoader, “x”, Bounce.easeOut, 500, 0, 1, true);

}
