Adding Relationship field to backend user registration form

Further to this, I've set both of these relationships to 'show as an admin column', and the relationships show up in the schools posts list, but not in the Users list - so it seems in general the user creation and listing parts are not behaving as expected.

Please note however, this is currently using the MetaBox Builder - I have not put the code into my plugin as yet. I tend to test things in the Builder first and then add the PHP once I'm happy with all the settings. I'm just mentioning this in case it might make a difference.

ah... thanks. The column name does the job - I still had the default 'title'.
Shame about the user registration page, but a good work around (for anyone who's interested) is to allow a New user to be created directly from the school post relationship field. This then creates the user and automatically creates the relationship as well...
