php de çözemediğim bir konu

Merhaba, alttaki kodda <tr> <td> lemede eksik bir kod kullanıyorum sanırım ön izlemede casma çıkıyor nerde hata yapmışım ( tablo yapısında ) belirtirseniz sevinirim.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^PHP KOD : ^^^^^^^^^^^^^^^^^^^^^^^^^
<table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="%100" id="AutoNumber1">
<tr>
<?php
$sql = 'SELECT g.g_isim,g.g_link,g.g_resim,g.g_date,g.g_acikla,c. cat_ismi FROM '. $table_oyyun .' g,'. $table_kategori .' c
WHERE g.g_kategori = c.cat_id
AND g.g_status = 1
ORDER BY RAND()
LIMIT 6';
$do_sql = do_mysql_query($sql);
while($row = mysql_fetch_array($do_sql)) {
if($counter == 1) { echo '<tr>'; }
?>
<td width="270" valign="top" class="content"><a href="<?= get_game_link($row['g_link']); ?>"><img src="http://www.sallamaoyun.com/thumb/<?= $row['g_resim']; ?>" alt="<?= $row['g_isim']; ?>" width="<?= $thumb_width; ?>" height="<?= $thumb_height; ?>" border="0"></a></td>
<?php
if($counter == 3) {
$counter = 0;
echo '</tr>';
}
++$counter;
}
?>
