Hi Charles: Well, in general, I use Sql Server but the procewss for this senario might be something like: You have the first combobox displayed. The user arrows up and down in the combo box. When they click on an item you display the second combo box with the desired items loaded from the database. To do that you initially set the second combo box to visable false. Then when the user clicks an entry in the first combo box, you use the selected item to access the desired entries from the base based on the item selected in the first combo box. That or you can use a button to do the same thing.

If I have a form with two comboboxes on it. The first combobox is automatically filled in with data. The second is filled with data: although it is a larger list than is needed. After you select the option you want from the first combobox, the second combobox should contain only those items related to the choice you made in the first combobox. For example, If you have 'a b c' in the first combobox AND YOU CHOOSE 'A', ONLY A 'D E F' SHOULD SHOW IN THE SECOND COMBOBOX. If you have a 'b' in the first combobox,, then a 'g h' should appear in the second combobox. If you have a 'c' in the first combobox, then an 'I j k l' should appear in the second combobox. How might I achieve this using tools in Access? Charles E. Black charlesblackusc@xxxxxxxxx
