[support] CCK type of 'person'

New to Drupal and trying something which should be easy. Using CCK to create a person type. Fields are to be lastname, firstname, DOB... CCK is forcing me to give each entry a title which doesn't see to make sense, unless I use the persons full name. But I'd rather have this in lastname, firstname fields. Is there a way to add a unique id in the title field and hide it from the public? ------------------------------------------------------------ John Furfey Digital Systems and Services Coordinator MBLWHOI Library Woods Hole MA 02543 USA PHONE: 508-289-7435 EMAIL: jfurfey@mbl.edu http://www.mblwhoilibrary.org
