CSS "No-Repeat" Isn't Working

Hi there,

I’m working on the following site: efpeterson.com/earlyinvestors and I have put a background that I want not to repeat. In the style sheet I have indicated this right after I call the background image, however it’s still tiling. Any ideas as how to get this to stop? You can view the stylesheet here: http://www.efpeterson.com/earlyinvestors/wp-content/themes/americana/style.css
