UILoader with preloader

[midjam]

Hi guys please help if you can.

I have a movieclip with a UILoader that loads an external .swf file and a preloader as it loads.

I need the UILoader to swap the .swf file when a buttoon is clicked this works fine with the code below and when I click the button the .swf will load but the preloader will not it just loads the first time i open the movieclip.

What do i need to add to refresh the preloader for each .swf file I want to load?

Cheers guys this is probably very simple but i`m very new to actionscript.

import fl.transitions.Tween;
import fl.transitions.easing.*;

var request:URLRequest = new URLRequest("photoGallery.swf");
myLoader.load(request);

bensTattoos_mc.addEventListener(MouseEvent.CLICK, bensBtn);

function bensBtn(event:MouseEvent):void{
// Play video Behavior
var request:URLRequest = new URLRequest("photoGallery.swf");
myLoader.load(request);
}

stop();
// preloader code
myLoader.addEventListener(Event.COMPLETE, fadeIn);

function fadeIn(e:Event):void
{
	preloader_mc.alpha=0;
	new Tween(myLoader,"alpha",Strong.easeOut,0,1,1,true);
}

myLoader.addEventListener(Event.COMPLETE, fadeIn);
change：
myLoader.contentLoaderInfo.addEventListener(Event. COMPLETE, fadeIn);

Thanks for the help but I get the following error.

1119: Access of possibly undefined property contentLoaderInfo through a reference with static type fl.containers:UILoader.

i'm sorry.
i make a mistake.

All you need to add "preloader_mc.alpha=1;" to "bensBtn" function.
