How to tell flash to play all SCENES in a movie RANDOMLY?

1

i am making a movie with 5 scenes. my intention is to ask the movie to play all 5 scenes randomly each time when a reflesh button is cliked. what i did so far was to tell the movie starts playing from scene 1 to scene 5, then click a refresh button to tell the movie play randomly. the problem now is, it may start from scene 4 and ends up at scene 5. Not a random play at all , isn’t it? so, can i make it starts from, say scene 2, than 1, 5, 4, 3, or something like that, but randomly? any advise would be greatful to me. thanks.
