Sorry about that.
I thought I had had it well explained.
The problem is I don't know where to set session[:checked] for when we
know the user has been to the check page. Setting it in the view seems
to not be functional, as does throwing a method into the helper. This
is the functionality I want:
session[:adult] == true
def adult # a method from a form on the page that sets the
session[:checked] (just makes sure the user has in fact been to that
if session[:checked] == true # how do i set this to *be* true???
session[:adult] = true
