Messed up my site, please help

I was editing ftp for the header for at www.talkhandhelds.com and now the site won't show up. LoL. Area I was editing is here (the first table tag isn't closed because it continues on later):

<table align="center" width="1001" cellspacing="0" cellpadding="0" border="0" bgcolor="#5F7D8E" background="./templates/Aeolus/images/hdr_bg.gif">
<tr>
<td width="100%" align="center" valign="middle"><table border="0" cellspacing="0" cellpadding="5" width="80%">
<td align="center" valign="middle">
<a href="index.php"><img src="http://www.talkhandhelds.com/forums/images/logo1.jpg" width="430" height160 border="0" /></a>
</td>
</table>
</td>
</tr>

you're using invalid markup, that's why.
put a = between height and 160.

Also put a closing tag for the initial table at the end. Or is this included?

No, that's not it. That just changed the logo size. For some reason the body of the forums won't show up.

Woohoo, fixed it. Somehow at the very bottom of the header part the end of an advertising got cut off and there was no > to finish the current tag and then no </a> to close it so it wouldn't load up the body of the forums.
