You might want to clean this up...
CSS Validation: FAILED 31 Errors
and this is what someone may have suggested cleaning up, using padding, margins, etc... it's not good practice to use alot of nonbreaking spaces to define your page areas.
HTML Code:
<p align="center">
<iframe src="http://flyingdesigns.idoo.com/googlead160x600.html" name="I1" width="160" height="600" scrolling= "no" frameborder="0" align="left"></iframe></p>

</td>
</tr>
</table>
</center>
</div>
</td>
I'm also not a real big fan of tables... YUK!!! you can accomplish this all through CSS, get away from tables & save yourself a big hassle later.
