I can't troubleshoot from the page code, it does not include the css.
When the page is uploaded to a server for testing i will be able to troubleshoot the css.
you could also troubleshoot this on your end using Fire Fox and the Fire Bug extension. Fire Bug allows you to select section of the page and see and edit the css for that section. using Fire Bug, you can find the CSS for the required section and try adding the right margin to it.
see this page for details on using Fire Bug:
