Thanks Paul! I'll try it on my form.
I didn't want to use a date control is because Users here tend to enter their date of birth in the format: 19092008.
For a date-field validation, Livecycle is not able to auto-format the date into 19/09/2008 like the numeric field does. The display and edit pattern in Livecycle doesn't seem to work even when i enter a DD/MM/YYYY format as the edit and display pattern. It only alerts the Users to enter date in DD/MM/YYYY rather than to format it automatically.
Unless, if you can help me with something like an auto-format script that can transform the date to 19/09/2008 whenever Users enter DOB as 19092008.
