Subform Value Does Not Display in Form (but will in table)

[GDCross]

I have an Instructors form with two tabs. In one tab called Courses, I have a
subform called sfrmInstructorCourses. Since an instructor can train many
courses, I have this subform displayed as a datasheet. In the subform, there
are two fields of interest, the course number combo box and non-standard
classes combo box. I have the subform designed such that if a XXX999 course
number is chosen (in which XXX can be any set of letters), the non-standard
classes combo will contain classes for that course number (one to many
relationship). All works great that is until I reopen the Instructors form as
the non-standard class field in the subform does not display any values. When
I reselect the course number, the correct non-standard class is displayed.
When I open the table containing this data, tblInstructorCourses, the correct
non-standard classes display. Can anyone help me figure out how to get the
non-standard class data to display when I open the Instructors form? Thanks
in advance.

Hi GD,

Open the appropriate table, and check to ensure that a foreign key value is
being written to the table, for the many-side records. Also, in form design
view, verify that the combo boxes that are not displaying data correctly have
the intended field specified as the Control Source.
