$comments = mysql_query("select count(id) as num_comments from comments where parent = " . $row["id"]) or die(mysql_error()); 
$num_comments = mysql_fetch_assoc($comments); 
$num_comments = $num_comments["num_comments"]; 
if ($i++ != 0) echo '<div class="hr"></div>'; 
echo '<p><a href="news.display.php?id='.$row['id'].'">'.$row['title'].'</a></p>';
