Credit card number is required error with Authorize.net

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?

Not sure why I thought the curly braces were required. That's been corrected, but now I'm on to the mysterious "The configuration with processor is invalid. Call Merchant Service Provider" error.

Hi jordanroher ,

From a quick Google it looks like the answer is to call your Merchant Service Provider.

Yep, Authorize.net is on it. Thanks, Bob. Once I get this ironed out I'll be buying a 3 domain subscription + A.net plugin.
