Hi
this confused me too. The problem is that that checkboxes in html do
not return anything when submitted unless they are checked. You need
to check web.input() for an entry corresponding to the name of the
checkbox. If there is no entry, then interpret this as unchecked. In
your example replace your return statement with the following:
'''return "Results: %s, %s" % (form['A'].get_value(),
form['B'].get_value())'''
formdata = web.input()
return formdata.has_key('A'), formdata.has_key('B')
