I'm afraid this is a little too complex for me to work out through this forum. Fixing your page and getting it working would be more appropriate for a premier support ticket.
No tables listed is usually a problem with your site definition. You might try toggling your connection in the interface to force it to refresh... or check to see if the tables show properly when creating a recordset.
If the tables do show in a recordset ui but not in the multiple insert, then that is something I can debug with you because it would be a bug in that interface of some sort. If that is the case, then please post a US phone number or Skype contact information in a reply and I'll schedule a phone call to debug why that is happening.
