If your credit card number's HTML input tag is named
'mv_credit_card_number', IC internals should take care of deciding if
it's OK.  If it isn't, you can tell with this:

[if type="explicit" compare="[error name='mv_credit_card_valid' keep='1']"]
not OK

on the landing page after the data's submission.  The same goes for
mv_credit_card_exp_month and mv_credit_card_exp_year, but I don't
think you can tell which of them there was a problem with.  I think
the mv_credit_card_valid error is set if there is a problem with any
of them.  It would definitely be nice to be able to tell which of the
fields there is a problem with.
