Do this instead:
if form.accepts(request.vars, session):
return len(request.vars.field)
I am not sure whether this should be considered a bug since the
process of supporting multiple fields with the same name is only
supported for checkboxes. I will look into this some more anyway.
I strongly suggest giving different names to the three INPUT fields
else you will not be able to reference them using validators (which
why this is not supported).
