mysql_fetch_row fejl?

Hey...

Får denne fejl:

Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in d:\webs\gi\www\go\medlemmer\admin\vis.php on line 132

-----------

Linien starter her:

while ($myrow = mysql_fetch_row($resultat)){

//Udskriv vores data - $myrow[0] er ID og de andre siger sig selv.. 1-2-3
echo "<table width='100%'><tr>";
echo "<td width='150'>Navn: <strong>$rows[1]</strong></td><td width='220'>Email: <strong>$rows[2]</strong></td><td width='80'> ID = <strong>$rows[0]</strong></td>";
echo "</td></tr></table><br>";
$count++;
}
