Hello again,
I'm pretty sure the first should be like this :
**********
def first():
if request.vars.visitor_name:
session.visitor_name = request.vars.visitor_name
redirect(URL('second'))
return dict(form=form)
**********
NOTICE THE return dict(form=form), I think it's what is missing at
this step in the book (one page later it's corrected with the
FORM(INPUT()) form creation technic.
I'm kind of a newbie too but I guess without this it's not really
postingback (?)
If it works for you we should try to be sure Massimo gets the error-
reporting (so newbies don't get lost ;-)) to gather some kind of
"erratum".
Cheers,
