I have been editing a simple html site for a client. Just simple things like adding contact information and such.

They have asked me to add the Google Map. Got the iFrame code from Google, created a div id for style (closed it too). Everything was beautiful for a couple hours. Now, the site main content box is no longer centered and it appears the width of the home page box may have been reduced somehow. Things are jumbled up - http://swbetz.com

I checked for missing brackets, divs that weren't closed. Any idea what could be causing this problem?
