Previous and Next buttons, First and Last buttons

I’m facing a problem and need help from anyone of you.

For example:
In a movie (swf) which has four buttons, first, back, next and last. Basically these button are used for navigation between movieclips. The function of these buttons are same as what usually we saw in a forum, which navigate between pages.

So, could anyone give me some idea what should be done?

Any help in the shape of tutorial or .fla file would be greatly appreaciated.

Thanks a lot.
