Dynamically Change the valign of a <td>

Hey all,
I am tring to dynamically change the vertical alignment of a <td> but am running into trouble:

<TD id="link5" name="link5" BGCOLOR="#000259">

<select name="valignleft" size="1" OnChange="window.document.all['link5'].valign='bottom' ">
<option value="top">Top</option>
<option value="middle">Middle</option>
<option value="Bottom">Bottom</option>
</select>

I can get this to work with background color and other things, but not with valign. I've tried verticalalign, and textalign to no avail! Any help would be appreciated.
Thanks

I would use style instead. This will work cross-browser too by the way (document.all is IE only I think):

Code:

---

<table><tr>
  <td style="vertical-align:bottom;" id="c1" onclick="document.getElementById('c1').style.verticalAlign = 'top';">asdasdasda</td>
  <td valign="top">asdasdasda<br>asdasdasdasdasda<br>asdasdasdasdasda<br>asdasd</td>
</tr></table>

---

Thanks!!!
