If you need to ensure that Enrollees fall within a specific age range, you can set parameters within the Program settings. Age restrictions on set on the Program level, NOT on the Class level.
NOTE: Age restrictions are based on the birthdate field of your Enroll Form. You have to have this field visible for age restrictions to work. If you create a different birthdate field, the age restrictions will NOT work.
You can set up a youngest and/or oldest age restriction. It will work if only one is set up.
You can also set a date to apply the age restriction, which is optional. If no date is selected in this step, the age restrictions will be enforced using the Enrollee's birthdate and the enrollment date.
