Need Help Editing Wordpress Column Width

I'm working with the following wordpress theme and I'm trying to remove the right middle column (the one with the video) and then expand the main middle column to fill the gap. I've removed the middle column but cannot find in the css where to expand the other column. Could anyone help me?

It can be downloaded here if you want to do that (http://www.mediafire.com/?zoc2ywm2gyk)

Thanks in advance for any advice on what to look for.

 

This is the line in header.php, just under the IE conditional comments:

<style type="text/css" media="screen"> #content { width: 400px; border: none; } </style>

Code (markup):

Change it to:

<style type="text/css" media="screen"> #content { width: 620px; border: none; } </style>

Code (markup):

 

Is the thing fixed? Coz, I cant find any problems over there... Kindly include a screenshot of what change you need if you dont mind.

Thanks.

 

Thank you so much for the help. That worked perfect. I just was not expecting it to be in the header file.

 

You're welcome! It is pretty weird to have it out on its own, I've never seen that done before.
If you like, you can remove that line and let the width be set by #content in style.css, but you also need to delete the border-top property.
