Ok, I've recently started to learn AS3 and I'm found out very quickly that it's a completely new ball game. Arrrrrrrghhhhhh Understatement

Can anyone help advance my learning a little in regards to this problem?

I have a few buttons on my main.swf which i want to use to load external movies. The problem I am having is that in AS2 I could just attach the AS to the button, but it seems in AS3 this is not the case?

How can I reference the specific buttons and from the AS? Considering that I am using 1 piece of code slightly modified for each button.

Code:
var imageRequest:URLRequest = new URLRequest("movie2.swf");
car imageLoader:Loader = new Loader();
imageLoader.load(imageRequest);
addChild(imageLoader);

imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);

function onComplete(event:Event):void
{
event.target.content.slidingpages.x -= 100;
}
Any help would be great as I'm at a complete loss on this. Thanks in Advance
