Redirection with Cookies

[Karl Gralowetz]

Hello, Scriptmasters!

I have a big Problem with some Javascript:
One a website, i want to paste some "confirm" there, if the
visitor's browserlanguage is not "de".
when he confirm, he'll be redirected to the translation of this page.

to store this information, because it's ugly to ask on every single
visit, if he want to switch to the translation.
but i can't find out, why the script isn't working.

i please you to look at the source and answer me, if you have some
solution(s).
thanks, karl!
