/**
 * CHANGES
 * v.1.2 - Fixed bug when nested fieldsets are used.
 * v.1.1 - Changed $(this).parent().children().filter( ELEMENTS HERE) to $(this).parent().children().not('label').  Prevents you from having to guess what elements will be in the fieldset.
 *
 * This script may be used by anyone, but please link back to me.
