Duplicate the main record and related detail records

Hello All!  I have run into an issue cloning records in Microsoft Access.  I have modified code from Allen Browne's website.  The code clone's the main record first after prompting the end user for a new date.  That part works flawlessly.  The problem arises when I get to the detail records.  All of the information for the detail records gets cloned; however I can't get the new date inserted into the records.  It leaves it as a null value which displays as 12/30/1899 in SQL Server 2005.  I believe it must have something to do with a date delimiter, but I am not quite sure.  Any help would be greatly appreciated.
