I have two forms, the first form has a drop down list and updates customer names on the form when a different customer is selected. I have a button that switchs to the second form, this form has contact information. On the second form I also have a button that switches back to the first form. When I go back to the first form and select a different client from the drop down list it does not update the form. Do I need to close the first form when going to the second and reopen from the second form?
