customer checkout page problem...
 

I'm wondering why the rest of my site will save the color mods I have made ..but when i go to the checkout section, the screen shows the defalt colors of the demo....
any help would be great...

Try saving your modified CSS file in skin1_original folder as well.

If your running on HTTPS for checkout make sure the CSS reference you are using is not absolute, i.e if you have it as http:blah.com/skin1/skin.css it won't load if your security settings block non secure elements.

Also worthwhile checking it from another net connection incase your ISP has an erraneous Cache of it. I've had ISP's cache sites for 48 hours to deal with their user loads which can cause chaos when developing a site and you don't see the latest update. (an ISP can cache a page even it the headers say not to)
