/*
 * 04/28/2002 - ST  - Check parts entered for garbage characters and quotes
 * 12/01/2002 - ST  - And fixed that!
 * 04/17/2004 - ??? - In showAPart, put "-->" after action 1 - to be removed later when storing in MySQL
 * 12/28/2006 - JL  - In partChange(), added auto-selection of first item for action/level 2 (and call descriptionChange())
 *                    and commented out showAPart() since descriptionChange() calls it anyway
 * 12/28/2006 - ??? - Modified addPart() to store the partnumber
 * 12/28/2006 - ??? - Modified finalChange(): changed definition of number:
 *                        box[].value has part number now, no longer index the index
 *                        selectedIndex is used now.
 *                    Also changed URL construction
 * 01/24/2007 - MC  - Require action 2
 * 07/24/2008 - JMH - Changed from document.forms[0] to document.forms["parts"]
 * 09/17/2008 - JMH - Changed from document.forms["parts"] to $("partsForm")
 *                    Code cleanup
 * 10/06/2008 - JMH - Added year/make/model/body code
 * 12/11/2009 - JLB - Some action2 parts require "one or more" action3's
