Glad to hear it :)

The web page and form response are two completely separate requests.
You can't think of them as a single request; in fact, it's entirely
possible for someone to send the POST request without first getting
the page at all.

Is it necessary to have them in my decorators as well, or is it that these values won't get passed around if they're not integrated in the decorators?

They won't get passed around. The only way to share that information
is via the page itself (or something along those lines, like a session
variable - which is some magic built on top of cookies). Think about
the two requests completely independently, and make sure that (a) the
GET request sends back the correct page, and (b) the POST request does
whatever it needs to, and sends back a new page.

Hopefully that should set you in the right direction!
