HELP with Flash 8 sliding menu tutorial

Hi there!

I just finished the sliding menu tutorial and it’s great but i am wanting to customize it and was wondering if any of you could help me.

what I am trying to accomplish is having only 2 buttons, a forward and a backward, instead of 4-5, etc… buttons to view my gallery of 5+ etc… images.

is this possible?
what would the actionscripting be?
