I would like to create an age field based on a users date of birth so that this age field can then be used to determine which fields they will then need to fill out. Does anyone have any ideas on the best way to do this from the date at which they are entering the data i.e. the system date?
I would ideal like the persons age in months and years to be displayed back on to the scree in the age field also.
I currently have the following fields.
- Date of birth, as a date
- Age, as text field.
Thanks in advance for your help.
