 * Modified by Steve Woodson on 7-12-2011 to valdate entered zipcodes to selected states
 * 
 * Use the new function 'validate_zip' below if the state isn't sent with the function 
 * call (old manual forms gneerally) and 'validate_zipstate' if it is sent (form builder 
 * forms). If state doesn't exist or is empty it will send an empty variable.
 * The commented 'validate_zip' function below is what was replaced on 7-12-2011
