Magic pages(menu) with next and previous?

I have a feeling this would be easy or has already been accomplished with someone who’s good at AS3… I was customizing “xml magic pages” which I found online, and doing pretty well with my limited knowledge. BUT I need to have “previous” and “next” buttons, so users won’t have to click each button (one section has 14 pages).

I learned how to name the dynamic buttons, but I still can’t use that info to show that page (or ultimately the next or previous page). Magic pages is free and easily found online, but I could post the code here (or my code).
