TEMPLATE 9 : css error

Hi All,

The css (stylesheet.css) show that :

a.arrow_link,a.arrow_link:hover {
background:transparent url(images/arrow.gif) no-repeat left;
color:#8f9d4c;
font-size: 1em;
padding-left: 10px;
padding-top: 3px;
padding-bottom: 3px;

}

There must be an error somewhere because the arrow isn't shown, even the pictures exists. The same error is shown on the online preview.

Thanks
