Combo boxes in record editing form
I have a form in a database I'm working on that has two combo boxes linked to fields in a table. The form they are on is to be used to edit entries to that table.
I'm using combo box controls for those fields because i want to limit the data entries the user could provide... the first combo box displays a customer's name, and writes their customer id to the table. the second combo box displays a list of all of that customer's account numbers.
the combo box controls show the right values, and the drop downs show the other possible values, but when you try to select another value (as the user would need to do if they had entered an incorrect customer or account), Access just beeps and does not change to the selected value.
Does anyone have any idea if there are any settings at the form level or control level that should be changed to allow editing using these combo boxes?
Thanks in advance,
