<div class="post">

				<a href="http://www.siteaddress.com/forum/showthread.php?threadid=<? echo($row[threadid]); ?>" class="link">Comments</a>(<strong><? echo($row[replycount]); ?></strong>)</td>
			</div>
		</div>
	</div>
<? } ?>

When I post a link, the link does this

http://www.siteaddress.com/Josh/"http://www.siteaddress.com/forums/downloads.php?do=file&id=4"

I have no idea how to make it properly post the correct address
