You actually *could* input data into those fields, but it wasn't
immediately obvious, because the field size was "4" and the
value was " ". You couldn't type anything in until you
backspaced over the spaces that were there by default.
UPDATE 2008-11-05: Make absolutely sure that those values
are 4 chars long (via JavaScript)
