Thanks torgosPizza,

Looked through the log files that get updated when I try to do the purchase.
No Error messages in them. They look normal.

Nothing in Watchdog ... maybe there should be a uc_watchdog?

I dumped $nvp_response and got the following:

Array
(
[TIMESTAMP] => 2008-01-07T20:37:09Z
[CORRELATIONID] => 51d6d2f7bfd51
[ACK] => Failure
[L_ERRORCODE0] => 15005
[L_SHORTMESSAGE0] => Processor Decline
[L_LONGMESSAGE0] => This transaction cannot be processed.
[L_SEVERITYCODE0] => Error
[VERSION] => 3.000000
[BUILD] => 1.0006
)

Based on error code: 15005

"The transaction was declined by the issuing bank,not PayPal.
The merchant should attempt another card"

Didn't think that I would get this from a sandbox personal-type
account. Anyone got this working? Can a sandbox personal-type
account (generated CC#) work on a live ubercart site?

Thanks,
