credit card validation in Able 7

[KCarlson]

I have been trying to get the card numbers to validate against card type using the creditcardvalidator used in the creditcardpaymentform.aspx in the checkout directory. I can get the acceptedcardtype="MasterCard" to work, but I cannot seem to get that to accept two card types, such as acceptedcardtype="MasterCard,Visa". Does anyone have any experience using that validator? I have only seen one reference to it in the forums, and can find no documentation on it.
