Scrolling. Anyone?

HELP US, PLEASE! Me and my brother are trying to create a platformer(thanks to Fire Maple Games for their helpful tutorial), but we don't know how to make the scene scroll. When we preview, the games only shows a certain amount of screen and when our actor Player 1 moves higher than what's visible, the camera won't follow it. We tried using the camera control feature for Player 1 and set the scene to Scrollable, but nothing works. PLEASE HELP!

Camera Control, from the Cookbook.
If you're feeling ambitious, check out this more advanced Parallax scrolling technique, from Utopian Games.
Good luck with the game!
