I am using 4 files: header, body, sidebar and footer.

Each has elements of the layout and it's really only the body that is any different, the header, sidebar and footer are shared across all pages.

Which is why it's driving me crazy, I cannot figure out why this page:
http://timwheatley.org
has the sidebar nicely at the side where it is meant to be...

and on any of the post pages:
http://timwheatley.org/2008/03/01/i-am-pleased-to-report/
the sidebar appears below the footer!?

Can anyone please see where the problem is in the code? I am sure the TD tags are in the right places for the sidebar to be in the right cell of the main table, but it just won't appear there and every time I try taking out TD tags to find the issue, it messes up the main page...

What's missing when viewing a post that's needed to pull that sidebar up there?

Hope someone can help, would really appreciate it!

Nevermind, I found it. A php conditional for wordpress was set to only show part of the table on the homepage.
