<code><verbatim>
<tr><td colspan="2">
Previous descriptions:<br /><hr />
<th1>wiki $comment</th1>
<hr />


Above:
<code><verbatim>
<tr><td align="right"></td><td>
<input type="submit" name="submit" value="Submit Changes" />
<input type="submit" name="cancel" value="Cancel" />

</table>

At the bottom.
