hi im trying to make a subform so that i can change the control that the birthdate field uses so that i can validate the date it submits.
i need to check if the date thet submit is less than 18 years ago ie they are under 18.
i tried attaching a compareValidator control but it says it cant validate it. im not sure if this is possible or not so i tried making a subform to run the birthdate using a text box ( i plan to attach an ajax calandar control to it ) but im getting an error message saying the field is read only - any ideas?
