Scene jumping

OKay i have this swf
and its packed with about 12 some scenes, and there are two buttons, a forward and a backward…

the forward button. on release will jump to the nextScene(), and like wise with the backwards button, i jumps to the prevScene()

but at then end, when i get to the last scene, the forward button wont restart me back at the first scene, is there some code or action script that when i get to the last scene, by pressing a button it will take me to the first scene?

i know this can easily done if i use movie clips for scenes, but i have a restriction and I MUST use scenes.

help? this shouldn’t be too hard :slight_smile:
