Could someone please help me?

[evil kev]

a quick fix should be if you change: <div class="smallfont" align="center">All times are GMT -6. The time now is <span class="time">08:01 PM</span>.</div> to: <div class="smallfont" align="center" style="clear:both;">All times are GMT -6. The time now is <span class="time">08:01 PM</span>.</div>

altho really you shouldn't be using two tables like that next to each other a much neater solution would be to have one table with that split into two so it would be <table cellspacing="0" cellpadding="0" width="100%" class="tborder">
<tr>
<td width="40%">
left content
</td>
<td width="60%">
right content
</td>
</tr>
</table>

and i dont think you'd have the same problem with that
