Attachmovie no longer works when I publish in version 7, does anyone know?

1

I am having a little problem in regard to the attach movie. I am publishing my movie as flash 7. This will not be for the internet but an internal network.

However my attach movie script no longer works


//Pop up help window (centrally on click)
onClipEvent (load) {
	function Help() {
		_parent.attachmovie("mc_help", "mc_help", 500);
		with (_parent.mc_help) {
			_x = _parent.mainTemplate._width/3.9;
			_y = _parent.mainTemplate._height/5.9;
		}
	}
}

I am assuming this script was depreciated when version 7 came out. Can anyone please help me to convert this.

This would be a gr8 help for a quick conversion.

Thanks in advance
