How to control multi layered slider with buttons?

Hello,

I am rather new to flash and AS. I made a slider with 5 slides(each slide in one layer,so a total of 5 layers) with each slide containing motion tweened text and movie clip symbols.
Each slide is of 100 frames length. I want to interact these slider with forward and backward buttons in it.I want the slider to go to previous slide if I click
backward button and next slide if i click forward button.
So I need a piece of action script code to get the desired result.

also I need status of the slider.I want to keep 5 circles at the bottom of the slider, each one highlighting with respect to current running slide.

Thanks in advance
Sanjay
