Details
In the Object Inspector, for the TierEdit selected, make sure the FieldType is set to Date. Then clear the DatePopUp check box, as shown on the following screen.

When clicked, the DatePopUp always defaults to today’s date, but in some cases this is not the ideal situation because the user needs to navigate to a different date, such as for the date of birth, and this can take time.
Clearing the DatePopup check box prevents the Date pop-up window from appearing on the form, so the user can simply modify the date by entering the correct value.
Additionally, you can set the value of a Date field by setting it to a calculation as shown on the following screen.
