I didn't realise what the problem was straight away, but what you probably want
to do is this:

  form = cgi.FieldStorage(keep_blank_values=1)

Where 'form' is the object you might use to read the values from the submitted
form. The problem is that without the 'keep_blank_values' option set, the
'FieldStorage' object discards "empty" values.
