How to constrain a date entry that allows an enumerator to input age between 15 to 24 years?

fixer une tranche d’âge dans un champs
c’est à dire une contrainte de ne pas permettre à l’enquêteur de saisir de façon supérieur ou inférieur (15 à 24ans)

Do you mean you wish to be able to constraint an input that is between the age range of 15 to 24 years?
