Howdy, you need to add what you took off of the sidebars and add that to the center content.
#leftSidebar {
width: 182px; and further down
#content div.padder.three {
float: left;
width: 526px;
border-left: 1px solid #542A0C;
margin-right: 226px;
If you take off 10 px from 182 and 10 off from margin-right 226,
they go to 172, 216. But you have to add the 20 px to width 526 + 20 = 546
