hello

is there a way to get SUM of COUNT(*) AS user_id of two tables in one query?
this code shows only table rtv ID : NAME but I need ID: NAME + COUNT SUMMARY

PHP Code:
$sql "SELECT blah.* FROM rtv AS blah LEFT JOIN (SELECT mes_id_fk, COUNT(*) AS user_id FROM vote_ip WHERE date> (NOW() - INTERVAL 2592000 SECOND) GROUP BY mes_id_fk) AS top_voted ON blah.id = top_voted.mes_id_fk ORDER BY top_voted.user_id DESC limit 5";
        
$result mysql_query($sql) or die(mysql_error());
        while(
$row mysql_fetch_array($result)){
        
        
$list .= "".$row[id].": ".$row[naslov]." <br>";
    } 
        echo 
$list
