[Javascript] RE: Cookies & drop-down menus...

Fri Aug 17 07:02:49 CDT 2001

one hint is that if it only set the cookie for the duration of the browser
session then the code that is being used to set the expiration date isn't
working. i wish i could give you the answer, but it's js and i'm pretty new
to it.

Cutter, thanks a ton for your help. One minor thing, tho'.

I put the code in as suggested. The drop down box worked but it 
didn't set the cookie. I tweaked it a little bit and it sort of 
worked. It set the cookie but only for the duration of the browser 
session. Could I trouble you to take a look at the code and tell me 
what I'm doing wrong? It would be greatly appreciated! Thanks a ton!!
