Next/Back buttons with scroller

Hi!
I am looking for an added next back function to add to the individual button scrolling in this movie clip:

http://www.czmandesign.com/slider

Oviously the next/back in the link are inactive. If there is a generic script for a series of button instances that would go next and back when on a given frame please let me know. I also know there are many ways to get this sliding effect, so if anyone has any tutorials of others that may be more useful please let me know. I am limited in my flash experience and skill although I would still like the function of externally loaded images. The source files for my project so far can be found here in the zip file: http://www.czmandesign.com/sliderfiles

Any help would be greatly appreciated, or any other ideas of how i could pull off this “google” type navigation with slider integrated.
Thanks
