belongs to a
different
customer.

Token value mismatch.
When your customer logs into PayPal, the PayPal
PayerID is associated with the Express Checkout
token. This error is caused by mixing tokens for
two different
PayerIDs. The Token and
PayerID returned for any particular customer by

DoExpressCheckoutPayment.
Verify that your programs are properly associating
the
Tokens and PayerIDs.

choose new
funding
sources.

PayPal to select new funding
