Hi @Nathan
Example 3 on the linked page won’t work in this case, as the query should be quite simple.
If I understand correctly, the ‘staff’ post type contains a user select field where 1 user is selected. Is this correct?
If so, then example 1 is what you shoudl look at.
The meta_value in this case is the ID of the user.
Does that help?
Thanks
E
