In your post there are several possibilities:

1.- It is not sucessfull
2.- its reject
3.- error page

The three possibilities are all completely different.

Not succesful: there was a problem getting the approval code from the bank

Its rejected: the card was declined (either by the shop/site or the bank)

Error page: communication error in the TCP/IP protocol making impossible to get a proper response of the transaction.

So the best is like novita said, make a printout of the not successful/rejection/error message so that you can address it with the bank or the shop/site in which you are trying to make the purchase.

Regards...best of luck!!!
