Flash xml menu and loading ext swfs

Hello Hello Hello!

I found some handy script on xml flash menu, in which I’ve modified the code to how I would like everything to look and behave. Only, because I am new to this business of not having anything on the timeline, I do not know how to set the menu buttons as links to external swfs. I would like the buttons (menu items) to load an external swf into a holder on click. Then I would like the menu to collapse as it does when another main menu is clicked.

Anyone care to take a look? Even some guiding words so I can learn would be helpful.
