Frame - Additional CSS Definitions

[hmccaig]

I posted this in the wrong forum.

So, here's my deal...my website looks like this:

http://www.mydigitalmuse.com

I want my forums to have the frame borders down the sides as well. Right now it's plain:

http://www.mydigitalmuse.com/chatter

I have noted the frame code and pasted where I think it should go - at the bottom of the Additional CSS Definitions, but it isn't taking.

#frame {
width: 880px;
text-align: left;
background: #89cdd0 url('http://www.mydigitalmuse.com/siteimages/background-mdm.jpg'); margin-left:auto; margin-right:auto;
layout:fill;
}
-->


So, any suggestions, help please! :)
