But I cant get it to work. All I get is a scrollbar with no scrollingfunction. Do I have to add some sort of actions to the scroll (was under the impression that it was done automatically)?
Ok, apparently there are two tutorials on the subject on this page - the one you linked to, and the one I link to above.
The one I read didnt include any actionsscript.
Anyway, I used a simple action attached to two buttons (up, down) - looks better than the grey scroll, but the functionality is a bit crude (one line a click - no autoscroll when holding button).
