function options_validate(&$form, &$form_state) {

  // It is very important to call the parent function here:
  parent::options_validate($form, $form_state);
  if (!preg_match('/^(?:\\-[0-9]{1,4}|[0-9]{4}):(?:[\\+\\-][0-9]{1,4}|[0-9]{4})$/', $form_state['values']['options']['year_range'])) {
    form_error($form['year_range'], t('Date year range must be in the format -9:+9, 2005:2010, -9:2010, or 2005:+9'));
  }
