attachMovie("Themovie","Newmovie"+level, level)
Alright, in order for this to work, use the properties of the movie clip, click export for actionscript, and have the name be Themovie. "Newmovie"+level gives it it's own unique tag, because if no two movies will be at the same level, if they are, the new one will delete the old one. So the id is actually Newmovie5 or something like that.
