Hi All,

I have a form with fields txtStudentRef txtAno and txtSemester.

There is also a subform to show the Details the student studies in my
school. On the subform are the same textboxes with the same information
and the student's details.

I have the Subform relationship as:

Master:txtStudentRef;txtAno;txtSemester
Child:txtStudentRef;txtAno;txtSemester

When I open the form, the form shows the details for that student during
 the semester of that year.

The problem is that there are several buttons that change the subform
shown. When I change forms, and then change back, the relationship
doesn't update if I change the semester and year in the mainform. It
works ok when I open the mainform and change things, but when I click
another button to show a different subform and then change back, it
won't update the subform to reflect the txtboxes on the mainform.

Any ideas what's going wrong?

Thanks

Jeff
