I get the following error when I try to submit the order:

"We were unable to process your credit card payment. Please verify your card details and try again. If the problem persists, contact us to complete your order."

When I look in the order history, I see this:

"Credit card declined: $0.00"

The actual amount is $10, but it doesn't seem to register.

I'm using this in the developer test mode, and I do have an active developer test account with Authorize.net.

I'm using version 0.8 with Ubercart 1.3 (UPDATE: I'm now using 0.81, no change)

As suggested above, I tried changing the "response delimiting character" from "," to "|", but it doesn't seem to change anything.

Any ideas on how I can further troubleshoot this?

Thanks,
Andrey.

UPDATE: Since upgrading to 0.81, I started getting Authorize.net developer receipts. They show the correct charge amount - $10. Everything else (the error and the 0 charge in orders) is the same, however.
