That's where the relational part comes into play.
You have both databases working correctly, yes? Or were there some other issues that still need to be dealt with?
Assuming everything is going okay, you'll need to add the "switch_to_" subroutines to db.cgi. The instructions are at http://www.jpdeni.com/.../Mods/relational.txt. If you need help with it, I'll need to know your field names for both databases. We'll work it out together.
Once we get the subroutines written, you can add code to sub html_record that will list the playlists for the DJ. It'll all fall into place.
