I finally figured it out, kinda… The items that were not filled on the repeater would come from the Members DB, and in a normal relational database the common field between the members database and the registry database (email). At run time the SQL would connect to the Members DB and retrieve the info.
I found out that for those fields, if I DIsconnected from Members DB and Connected to the Registry DB and scroll all the way to the bottom After the Registry fields are shown, it shows the [email] fieldnames from the Membershp DB. Again, my previous experience in traditional relational databases got in the way!
