I added a page to a 3 page form based on a query

Page 4 of the form requires the data from a separate table

I add that table to the query (which previously had 3 tables in it) and when I add the table and select the fields to add them to the query, it still will not allow me to use those fields in the control for the text boxes associated with them on page 4 of the form.....

All the tables have a common key - it is the primary key for the main table and a relationship was created (by me) from the other 3.... yet, my new table's form page still behaves differently than the others.....

any ideas?
