I created a navigation form: a form that isn't tied to a database, filled with buttons that open other forms.
One of these buttons opens a parent-child table form similar to the Lesson 2 form:

I used Map Fields to connect the parent / child tables on the form.
When I open the parent-child table form from the navigation form ... the parent-child form opens; the parent records are accessible; however, the child records do not change when one navigates through the parent records. They are "stuck" on the first parent record displayed.
I attached the navigation form to the datasource. No change. I attached the navigation form to the table that has the most relationships. No change.
If I directly open the parent / child table form via Execute, the form works.
