I have successfully synchronize two combo boxes on a subform named as suborderdetail and the master form is frmorderentry. The two combo boxes is cbocategory and cboproduct. Unfortunately, when I try to enter the orderdetail and to make selection in list of the category and products, all the rest of the records changed and became exactly the same as the latest entry I just made. For instance, when I enter in the 10th order with cat-A, prod-a, all my previous entries and the entries that I have not made, they all shows cat-A, prod-a. Please kindly advice what should I do?I want every single entry is kept as I selected from the list of those two combo boxes.
