problem with db function php

hi

echo '<table>';
$requete = mysql_query("SELECT liv_nolivre, sec_nosection,
liv_commentaire, liv_titre FROM livre");


if ( mysql_num_rows($requete) != 0 )
{
while ($requete = mysql_fetch_assoc($requete)) {
echo'<tr class="tabtitre"><td>'.$requete["liv_titre"].'</td></tr>',
'<tr><td>'.$requete["liv_commentaire"].' </td></tr>';
}
}
echo '</table>';

i get:


Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL
result resource

any idea?

maybe my echo is not good?

Here you replaced your result set with an array. $requete is being assigned.
