Left column problems

I have been working on a column on the left side of my site so I can add links, sponsors. Basically what I did was add a left table in the header in the admin control panel. Started the right column where the forum should generate and closed that in the footer. Everything worked fine in the homepage. Looked real nice. Technically this should work throught all the pages in my fourm.

The problem is when viewing a thread. When I went to a particular thread, it moved the thread down under the left column. If you didnt scrool the page looks empty.

Any advice on this,

Thanks

I just played around with it a little more. The homepage of the fourm works great with the left column. but everytime I go to a thread it relocates it under the left column.

I took a look at the source and it is like the showthread is generating a few lines of code to close the tables from my header before the thread. This is making the thread move under the left column I think. Now I just need to get rid of it.

Thanks
