问题 I have a table (id, Name, Surname, Address etc.). All the fields (except id) can be NULL. I want to make a form where I can find all the records that have at least a NULL field. I have made a query (with the query designer) and then I "linked" a continuous form to it. In the Detail part of the form I put a textbox ID (linked to the query) so I can have all the IDs that have at least a field NULL. So far so good, it works. I would like to inform the user, after the ID, which fields are blank.
