That shouldn't be correct either if you coded it correctly. You should have:
HTML Code:
</td>
</tr>
</table>
Closing the content container somewhere in the footer depending on how it is to work.
Basically you should have a 2 column table (or 3 if you want a spacer). The $_phpinclude_output variable would be housed in the right column. The table would be closed in the footer for everything to be correct throughout the site.
