When you’re working with FileMaker Pro value lists, there are only a few situations which dictate how and where you should connect things up. In most cases, you create the value list right within the context of where you’re presenting the data. This means you use the table occurrences which are already connected. However, in some cases, it’s best to create a new table occurrence group and keep your value lists separate. This allows your FileMaker Pro solution to be maintained that much easier.
