This week, we are cascading into action with cascading combo boxes in MS Access. Also known as drop-down lists, combo boxes can be made to cascade in many interesting ways. For example, you might choose a manufacturing assembly in one combo box and then have the next combo show only the parts for that assembly. In this video, we are going to demonstrate a combo box trio that will let you select country, then region of that country, then city from that region. Many thanks to viewer @pilotgarry for the request to make this video.
