It appears that the DPS plugin on the payment form is unable to handle amounts greater than $999. If there is a comma in the total amount then the amount forwarded to payment express is just the digits up to the comma. Or it could be that Payment Express is ignoring everything from the comma, I have no way of telling the difference. Either way, it seems that the total field needs to be formatted without the thousands separator. Is there something might be doing wrong in the configuration?
