CSS changes/skins

Hi, I was successfully able to get the site working properly with the nameserver, and I was able to log in to the admin area (THANKS!). Question: I have made some color changes to wp-layout.css, and uploaded the changed layout to my server; however, none of the changes seem to have been made when viewing http://www.rightonred.net (my URL). Is there something else I need to do for my changes to show up? Thanks again!
