Clear date field if validation fails

Hello,

I am using LiveCycle Designer version 8.2.1.  I have several date fields that the user can select the date from the calendar or enter the date manually.  The validation field is (MM/DD/YYYY).  Is there a way to clear the date field if the user inputs the wrong date format?  After the error validation message displays, the incorrect data remains in the date field.  I would like to make the date field blank if the date is inputted incorrectly until the date is typed in the correct format.

If this is not possible, is there a way to just make the user only use the calendar to select the date?

I am a novice user.

Thanks in advance!
