Menu with infinite scroll question

hi,
i’m attempting to write a menu which uses two buttons to allow scrolling back and forth, but i can’t find a way to make it loop infinitely since there are a finite choice of selections. the fla is too large to attach so i can’t show you what’s going on unless you wanted me to send it to you outside the forum…

what i need to happen is this… i have a scroll limit set for a movie clip (_x)… once the _x of the movieclip is met, the button the user is clicking no longer works and the user is forced to use the other button to scroll back… what i’d like to happen is have the menu loop once the user hits that scroll position… but i can’t do it without there being an ugly visual jump in the movie… it’s really a pain in the ***.

any help or ideas are appreciated!

thanks in advance!
