OK, here's what you do:
First of all, stop uploading huge documents that take half an hour to download on a modem. Just describe what you've done.
And you know what, since even the size of the entirety of GameDev is less than the document, it would be smaller to download a full installation of the game with dummy sounds. Even better yet would be to just upload the .GDP file.
Okay, so now... define each music clip, then switch over to the Assign Media tab, and choose the map you are working with. Then, choose the function that activates, and choose the music you want to play in the "Change Background Music" dropdown list.
If that's what you already did and it shows that in the rtf file, sorry. I didn't download it. Make sure you are saving it and the functions aren't automatically activating another funciton that changes the music back. For refference, see the
tutorial.
