My report that is made shows how many days the person has been in the campground in the past 30 days. I would like for the message box to tell the user if they can stay anymore days and how many. Our rule for this database is that the camper cannot stay more than 14 days in a 30 day period. The report only shows how many days they have stayed in the 30 day period not the total amount of days they can stay on that date.
