Your form returns the date as an empty string "" which is an invalid date.
MySQL sets all invalid dates to 0000-00-00.  There is a big difference
between an empty string and NULL.  If you want to insert NULL into the MySQL
date field you will need to insert "/0" which is the escape sequence for
NULL.

In the script that inserts the form data just add something like:
if ($Date == "") $Date = "/0";
somewhere before the insert.
