Vertical tsunami menu

Hi all,
i have downloaded this flash file http://www.freeflashcomponents.net/flash-menus/tsunami-vertical-xml-menu-as3.html and i’m trying to make my own tsunami menu based on that one. but i have an issue. in the file there is a movie clip called “menuitem”. i can only see it in the library and not on the satge. so i don’t know where to place it.

any help is more than welcome!

thanks!
