My form collects the person’s date of birth (via the calendar dropdown). The next field along wants the person’s current age. This can be calculated by subtracting d.o.b. from today’s date. In fact you have a default value of [date] which should return today’s date.
However, when I subtract the one from the other I get a ridiculous negative number. it doesn’t seem to be numbers of days or years. what is it and how can I get a decimalised age? (ie: 35.4).
