    Use the birthday of the person to calculate age. Add a if condition to check your condition and throw an alert.

    Refer to Guido's blog for Age calculation.

    Hope this helps!

    I am thinking u can do with javascirpt. just you have take the value crom Birthday and check it, then popup the desire msg.

    function CalculateAge(birthday, ondate) {
   // if ondate is not specified consider today's date
   if (ondate == null) { ondate = new Date(); }
   // if the supplied date is before the birthday returns 0
   if (ondate < birthday) { return 0; }
   var age = ondate.getFullYear() - birthday.getFullYear();
   if (birthday.getMonth() > ondate.getMonth() || (birthday.getMonth() == ondate.getMonth() && birthday.getDate() > ondate.getDate())) { age--; }
  if(age>18)
    	{
    		alert('msg');
    	}
}
    thanks
    regard
