  $res = sql_query("SELECT * FROM polls ORDER BY added DESC LIMIT 1") or sqlerr(__FILE__, __LINE__);
  if($pollok=(mysql_num_rows($res))) {
          $arr = mysql_fetch_assoc($res);
          $pollid = $arr["id"];
          $userid = $CURUSER["id"];
          $question = $arr["question"];
          $o = array($arr["option0"], $arr["option1"], $arr["option2"], $arr["option3"], $arr["option4"],
