Hi Kurt. Thanks that was it. I removed the orphans and it works fine now.

>   WHERE t1.id IS NULL

>>In the database diagram tool, I am attempting to creat a relationship betwen two tables. When I look at the constraints for both tables, I there are none listed. Clinserv is the parent table with a 1 to many relationship with the child table clinsdet. Clinsdet.fk_clinserv is a field with an index on it (IE the foreign key). I want to relat this to clinserv.id which is a primary key. I can drap clinsdet.fk_clinserv and drop it onto clinserv.id. When I save the diagram I get the following error.
