I have been looking all over google and its newgroups on how to do this. I haven't yet found a full proof way. I am looking to take a combo box "Category" that has fields such as computer, monitor, printer, etc..., and once a user makes a selection, the combo box below it called "Model" will display the correct info. For example, if a user selects "Monitor" from the "Category" combo box, the combo box "Model" should only display monitors, not pc or printers. Thanks for any help.
