Anyone know how we can add more detail or change the style for credit card error messages? I can't seem to see how to do this in the cs file, and don't see an XML package that controls the display for the checkoutpayment page.
Basically, instead of the customer just seeing that there is an "AVS mismatch", I'd like to include a message that they call their bank, and provide more assistance, or a link to a troubleshooting page. I'd also like to change the font, because some people are claiming they aren't seeing the message.
