[Javascript] Cookies & drop down menus

Thu Aug 16 10:03:43 CDT 2001

I have this code that's meant to select a region's site and go to it. 
The next time you enter, it brings you directly there.

Now, I've gotten this to work with radio buttons and check boxes. My 
silly question is: how do I get it to work with a drop-down box. Many 
thanks in advance.
