Ok, I moved it back to where I had it originally:
http://67.20.92.91/store/cart.php
#center {
/* .menu-dialog .content a:link, .menu-dialog .content a:visited, .menu-dialog .content a:link { */
background:url(images/fashion_mosaic/bg-repeat-center.png) repeat-y top center;
}
Still trying to try some things too, but so far, nothing has worked.
