I'm trying to create a database of Publications (instruction manuals) where one publication is a modification to a parent modification. I'm storing all 'publications' in one table for better maintenance. This means that I have to use a Self-Join if I want to make one the parent, and one the child. Fundamentally this is no different than the Employee/Supervisor example I've found in many places:

I created a query with two copies of the same table with the 2nd one renamed for easier viewing. The query final comes up, but when I choose "ParentPub", it doesn't give me a drop down showing the other pubs so that I can choose one to be the parent.
What did I do wrong? I should be able to open up the table 'tblPubs', and get a drop down menu showing me all the pubs I can assign as a parent.
Thank you for your help,
Enrique
