Is question the same page that displays the link? If not you do not
need the redirection because you can make the decrement via ajax.
Otherwide:
form[0][-1][1].append(INPUT(_type='button',_value=T('Previous')
,_onclick='document.location="%s"'
%URL("question2")))
def question2():
session.current_item -=1
redirect(URL('question'))
how this helps.
