I have a database that requires the following validation applied to it.
When I enter the date of birth, I want that field to be validated so a message appears saying, "You must be aged between 17 and 64.", if a particular person is under 17 and over 64 years old.
I also have an age field defined, which calculates the age of a person once the date of birth is entered, but I cannot get it to validate and produce the above message.
Any solutions appreciated.
