more help with w3 validation needed, HELP!

[tipoboy]

ok guys i need some help again, i'm running some side column navigation using this code in my header:


Code:
<table border="0" width="100%" cellspacing="0" cellpadding="0" align="center"><tr><td class="sidecolumn"><table border="0" width="100%" align="left" cellspacing="1" cellpadding="1">$forumhome_sidecolumn_left</table></td><td width="2px"></td><td class="maincontent">
and this code in my footer:


Code:
</td></tr></table>
so the side column shows on every page.

now i get 12 errors on my memberslist and calendar page using the w3 validator and if i remove this code the errors go away, so if someone could be so kind to point me in the right direction i'd appreciate the help

the errors from w3.org i get can be found here:

any help is very much appreciated
