So you shoudl do
def update_form():
if not (club and address and nfas and persoon):
session.flash = "You have been redirected because you did not
supply all of the correct data"
redirect(URL(r=request, a='init', c='clublocator', f='application_form'))
return dict(form=form)
Then there is nothing else you need to do, when they see the next
page, web2py will replace response.flash with what is in
session.flash, and they will see the message.
