Hello Everyone, and thanks ahead of time for any help

I'm having a problem with a page, my CSS container is cut off at the bottom left, I think it has something to do with my iframe auto resize script. Any help would be appreciated, I'm stumped!

Example:

(URL address blocked: See forum rules)=dtcemail

Code:
<CENTER><IMG SRC="/n0csw.png"></CENTER>


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"(URL address blocked: See forum rules)">
<html xmlns="(URL address blocked: See forum rules)"
xml:lang="en"
lang="en">
<head>

<title>
n0csw.com hosting control panel
</title>
<meta http-equiv="Content-Type" content="text/html; charset=us-ascii" />
<meta name="title" content="n0csw.com Hosting" />
<style type="text/css">
