I think ceco meant he wanted to play a sencond movie after the first one ends.
If this is the case, then i suggest to load both movies in a main swf.
1 - MAIN MOVIE LOADS first.swf
loadMovieNum("first.swf", 10); //parameters: (movie path, level)
(this code goes in the main movie)
2 - FIRST MOVIE (first.swf) loads the second movie in its last frame.
(this code goes in the first movie)
I hope that helps.
