Does anyone have any idea why Zen-Cart changes my css on the fly.

I have been trying to apply a background image to my site http://gscoffeeclub.com/store/ and for some reason it keeps changing it to transparent.

This is what I have in my css file:
Code:
body {
    background:url(/includes/templates/gscoffeeclub/images/til_1.jpg) repeat;
    color: #666666;
    margin-left: 5%;
    margin-right:5%;
    width: 90%;
    }
This is what firebug gets when I am looking at the page:
Code:
body {
background:transparent url(/includes/templates/gscoffeeclub/images/til_1.jpg) repeat scroll 0%;
color:#666666;
margin-left:5%;
margin-right:5%;
width:90%;
}
I have deleted all other css files in all of the other template folders just in case they might be getting loaded after the main file and I am still getting this change. I have also checked and rechecked a dozen times to be sure that the image is where it is supposed to be. This one has me stumped.

Anybody have any ideas?


Thanks,

Gary
