First, it looks like you are using unloadMovieNum() unnecessarily. The global loadMovieNum() loads the movie into the player level specified, replacing the movie that was already loaded at that level. It's usually only necessary to unload a movie if you have loaded a swf into a player level higher than 0, and it obscures the swf's at the lower levels, or when you simply aren't going to have any further need for the movie you've loaded a higher level.

In the code below, you might have an addressing problem, but it's hard to say without seeing the liv. "this." would refer to the button movie clip. If your "introduction_movie.swf" is loaded into the button itself, it will work, but if it's loaded into a placeholder on button's timeline, or another timeline, or on another level, it won't, so that swf might not be unloaded at all.

this.unloadmovie("introduction_movie.swf");
