User Story
As a user, I want to ensure that the birthdate of a person entered in the system is not a future date, so that I can maintain accurate and valid records.
When entering a person's birthdate into the system, I expect to receive an error message if the date entered is a future date. The system should compare the birthdate entered with the current date using the TODAY() function, and if the birthdate is later than the current date, the system should display an error message indicating that the date entered is invalid.
This validation rule will help me to maintain accurate and reliable data in the system, and ensure that I am not mistakenly recording future birthdates for individuals.
