I'm getting the error "(TESTMODE) Credit card number is required" with the Authorize.net form submission event. I've very carefully typed in {credit_card_number} into the Card's number field in the event configuration, but no matter what I actually enter in the credit card field, I always get that error. The API and Transaction key are correct, ChronoEngine is set to TESTING: NO, but it never works.
What could I be doing wrong?
