Kirupa tutorial problem?

I have been following claudio’s tutorial on creationin a transition and preloader.

However for some reason my movie will not play the “opening” sequence so that the swf file behind the transition is visible.

I’ve included the file so hopefully someone could help me, please.

One think I have noticed is that the function command looks for “_root.section” and I don;t know if this is action script or if it is looking for a label?
