[PHP]Problem z modułem Opcje

[partoles]

Witam,
Napisałem moduł i pojawia się następujący błąd:

[PHP] pobierz, plaintext 
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/pit36/domains/sm.ayz.pl/public_html/londyn/myslodsiewnia.php on line 67

function mysli(){
 
 
$z="SELECT * FROM `hcws` WHERE `co`='dane' ORDER BY data DESC";
$w=mysql_query($z);
echo'<ol>';
[b]67 linia -[/b] while($r=mysql_fetch_array($w))
{
echo("
<b>I</b>mie: <i>".$r['imie']." </i> <br>
<b>T</b>resc: <br>".$r['tresc']."
 
");
}
echo'</ol>';
}

A więc, poszukałem w internecie shoutboxa i znalazłem, ale problem polega na tym że nie wiem jak dodać pytanie chroniące przed botem, jak dodam je w innym module to wywala błędy.
Kod Shoutboxa:
