Xml and flash navigation

I did this tutorial http://www.kirupa.com/developer/actionscript/xml_dropdown_menu.htm

which is very good but i’m trying to get the navigation to load external .swfs
into the same swf file. I created this in the actionscript but i’m not sure its correct

Actions.loadMovieNum = function(loadVar){
loadMovieNum(loadVar,"_self");
};

and added this to the xml file thinking it could insert the AS script (this is in the XML)
<item name=“forums” action=“loadMov” variables=“about.swf”,“level1”,“GET”";/>

I know something wrong maybe someone can point me in the right direction
thanks.
