If ( DateExpired > Get ( CurrentDate ) ; "Expired" ; "Current" )
Make this an unstored calculation field or it will not update with each new day.
Format the unstored calculation field to make give it a check boxes format with "Expired", "Current" as the two values in its custom value lists.
Works like a charm thanks again!
Please note that two check boxes imply to the user that both values could be selected--which makes no sense here. I would be a better interface design to use a radio button format--which implies that only one value at a time may be selected, instead of check boxes.
