Multivalued Fields are brand-new to Access 2007. A Multivalued Field allows you to create a field that holds, literally, multiple values. This is great for creating a field that displays a list.
For instance, if you need to track which projects each employee is working on, you can use a Multivalued Field to list all projects for one employee in ONE FIELD. What’s more, Access 2007 makes adding items from a multivalued list as easy as clicking a few checkboxes.
