I installed the files and now I can see the admin site has drop down on the top left of the screen. On the customer site everything stays in English and I can't see where I can switch over to spanish. I don't know if this is done with a browser setting, microsoft windows/ mac osx setting, or I don't have something installed correctly. How do I switch my test site to the spanish version?

under the admin I added the language with the following settings.
Name: Espanol
Code: es
Image: icon.gif
Directory: spanish
Sort Order:0

the actual site if you need to see it is http://onlineorder.sshorepizza.com

Thank you for your help!
