Professional :: Host Movie - Several Buttons In One File

I am creating a Host movie, where 5-6 buttons will be loaded from. However, I am having difficulties coding each button to open an swf file. Here is the code I have to try and load my ipod button.

stop();
ipod_btn.addEventListener(MouseEvent.CLICK,ipod_btn);
function ipod_btn(event:MouseEvent) {var request:URLRequest = new URLRequest("ipod.swf");
var loader:Loader = new Loader()loader.load(request);
addChild(loader);}

However, it doesn't do anything and I get these compiler errors
1023: Incompatible override.
1021: Duplicate function definition.
