Problem med Sql script

Hej alle....... nu har jeg sq et problem igen...( 2 idag )

ok mit script ser således ud:


<?php
include ("config.php");
mysql_connect($host,$user,$pass);
mysql_select_db($db);
$query = mysql_query("SELECT * FROM community WHERE navn='$s_navn' AND password='$s_password'") or print mysql_error();
while($r = mysql_fetch_array($query)) {
$navn = $r["navn"];
$znavn = $r["znavn"];
}
$hentnye = mysql_query("select * from beskedtilanders WHERE navn='$znavn' AND set='NULL' ORDER BY date DESC LIMIT 0,10") or die(mysql_error());
while ($ud = mysql_fetch_array($hentnye)) {
extract($ud);
echo "
<table>
<tr><td align='center'><b>Nye Beskeder</b></td></tr>
<tr><td>Besked fra: <b>$fra</b></td><td>Modtaget: $date</td></tr>
<tr><td><i>$overskrift</i></td></tr>
<tr><td>$besked</td></tr>
<tr><td></td></tr>
";
}
echo "</table>";
$hent = mysql_query("select * from beskedtilanders WHERE navn='$znavn' AND set='NULL' ORDER BY date DESC LIMIT 0,10") or die(mysql_error());
while ($ud2 = mysql_fetch_array($hent)) {
extract($ud2);
echo "
<table>
<tr><td align='center'><i>Gamle beskeder</i></td></tr>
<tr><td>Besked fra: <b>$fra</b></td><td>Modtaget: $date</td></tr>
<tr><td><i>$overskrift</i></td></tr>
<tr><td>$besked</td></tr>
<tr><td></td></tr>
";
}
echo "</table>";
?>

fejlen ser sådan ud!:


You have an error in your SQL syntax near 'set='NULL' ORDER BY date DESC LIMIT 0,10' at line 1


nogle der kan se fejlen....???? (help)
