Sage 100

Customer is on 4.4.6 using Sage Payment Solutions. For one customer, she cannot authorize or process the credit card. She gets a pop up window that is blank. I'm guessing it is some sort of decline message but she said she gets other decline messages. Ideas?

Apparently, you cannot have symbols in address lines of a credit card. This one had % for c/o. Deleted the symbol and it processed.

FYI, this same issue - a percentage symbol in the credit card address line - caused another customer's FOUR cards to all be declined - something about the expiration. Removed the symbol and they were fine....
