Display restricted countries in product page

Hello,

I uncommented theme_uc_restrict_shipping and modified code a little bit:

function theme_uc_restrict_shipping($node) {
  $unshippable = array();

  if ($node->rs_data) {
    if ($node->rs_mode == 0) {
      foreach ($node->rs_data as $country => $state) {
        if ($state == 0) {
         $unshippable[] = $country;
        }
      }
    } elseif ($node->rs_mode == 1) {
      foreach ($node->rs_data as $country => $state) {
        if ($state == 1) {
         $unshippable[] = $country;
        }
      }
    }
  }
  if (!empty($unshippable)) {
  $country_names = array();
  $result = db_query("SELECT country_name FROM {uc_countries} WHERE country_id IN (%s) ORDER BY country_name ASC", implode(',', $unshippable));
  while ($row = db_fetch_object($result)) {
    $country_names[] = $row->country_name;
  }

  $rs_unshippable = implode(', ', $country_names);
  $output = t('This product is not shippable to: !countries.', array('!countries' => '<span>' . $rs_unshippable . '</span>'));
     return '<div class="uc_restrict_shipping">'. $output .'</div>';
  } else {
     return '<div class="uc_restrict_shipping">This item is not restricted for shipping.</div>';
 }
}

Unfortunately, I cannot see any
