A family of Microsoft relational database management systems designed for ease of use.
Please post the SQL view of the recordsource of the form and the rowsources of the four combo boxes.
The relationship DOESN'T ACTUALLY MATTER at this point. You do need the relationships, but they won't affect how the form works!
My idea was that you would have tblTablenames with fields (I don't remember and can't scroll back to see them) for AccessDatabaseID, ODBCID, SQLDatabaseID and ServerID, as the Recordsource for your form; the form would not have ANY other tables involved at all. It would have a textbox for the table name and four combo boxes, based on the appropriate tables (AccessDatabases, ODBC, SQLDatabases, Servers) and bound to those four ID fields. You would type in the tablename, and then select the appropriate choices from the four combo boxes. Then you'ld move to the next tablename, and so on.
I haven't any trace of a clue what you mean by "it doesn't work... it shows four records at the bottom".
Again: If you're basing the Form on this multitable query, DON'T. That's not how relationships work, that's not how forms work!!!!
