A family of Microsoft relational database management systems designed for ease of use.
I have a combo box that until yesterday worked fine. It lists various items and should allow me to add a new item from a list. This no longer happens. If I try to do this, it just shows the first original item and won't allow me to add new.
To allow a comboobox to add new items to the list requires code. So, there is likely to be code in the NotInList event of the combo. You need to look at that code, debug it by stepping through the code and find out what is happening or not happening
