1. The most common cause of this error is entering a $ sign as part of the amount. Simply enter the actual amount, e.g. 111.25.
2. If you entered the amount correctly, the most likely cause is that the card holder's bank is rejecting the card due to the amount. While rare, this can happen when the amount is larger than the customer normally charges and caused the bank's computer system to flag the transaction.
