Does anyone have a clue to what the "Market Type"
that cannot be processed is or how to get around the problem?
That's a configuration issue inside the merchant's Authorize.net account, which must be addressed by Authorize.net staff along with the merchant.
There's nothing you can do about it apart from that.
