Как да оправя този код

[sianbg2]

<?
include ("config.php");
function secure($var) {
return addslashes(htmlspecialchars($var));
}
$select = mysql_query("SELECT * FROM news ORDER BY id DESC")or die(mysql_error()); 
$num = mysql_num_rows($select); 
$cat = secure($_GET['cat']);
$vid = secure($_GET['vid']);
$sql = mysql_query("SELECT * FROM news WHERE cat='$cat'");
$sql2 = mysql_query("SELECT * FROM news WHERE cat='$vid'");
$fail = "files/$file"; 
$size = filesize($fail); 
while($r = mysql_fetch_assoc($sql)($sql2)){
echo '
rezultati
 ';
}

?>

В този ред ми е грешката,но как да я оправя.

while($r = mysql_fetch_assoc($sql)($sql2)){

Искам при изкарване на резултати да се пиши в браузера news.php?cat=kategoriq?vid=vida или нещо такова

Не изкарва никакви резултати дори когато напиша само news.php?cat=kategoriq

Не просто не изкарва никакви резултати.Все едно няма такава категория.
