    if (strstr($key, 'viewport_') && $key != 'viewport_user_scalable') {
      if (strstr($value, ',')) {
        form_set_error($key, t('Commas are not allowed for the %field_name field.
        Please, ensure you are using dots (".") when entering decimal values,
        and avoid any commas after the values', array(
          '%field_name' => $form['viewport'][$key]['#title'],
        )));
