Power CMS Content Changed width on pages??

I am adding new pages to a site and adding in the Powe CMS editor...all of my pages seem to be working fine, except one of them. IT appears that the content that is in the CMS for that page has forced the width of the container to change, pushing the side menu to the right and screwing up the design. That is the only thing I can think of as the other pages I created are the same coding, the only change is the CMS insert code and the title image.

Please help! How can I prevent the width from changing?

The page that is giving me the problem is:
guestspeakers.php

Pages created fine are:
mission.php

board.php

Many thanks!

I think i got this figured out...when I copied and pasted the word document the client gave me for this page, I also copied and pasted a table that he created and I think this had different widths and changed the coding...once I removed the table and recopied the straight text it seemed to work ok.

this must be the culprit. you want to save the file as plain text which takes all the code out…then you can copy/paste
