What can I do?

Thank you.

I'm having a sort of similar issue, I think. I can't seem to change the page width, it's not the 960px that it says it is in the template manager, so when I try to put in a fourth module across it wraps underneath. See: http://billbradbury.com/site/

Can anyone help with this? Think that I'm missing something simple and obvious
