Action Script Help

Hey guys, I was wondering if you could help me.
I’m making an interactive kind of game, and I want a number of scenes to change once the user has looked at each once.
For example, they go into three different scenes. When they finish looking at them all, Flash records this, and then when they look back at each scene again, they’ve all changed.
Anyone know a tutorial for this, or can show me themselves? :slight_smile:
