[url removed, login to view] - this site uses an [url removed, login to view] plugin that doesn't return an error if you put in the wrong credit card information. It will let you complete the order. I need it to show an error on the payment page. Also I don't think it validates the credit card holders address. I need this done TODAY!
If this can't be done then the shopping cart need to be switched with Virtuemart.
THIS IS URGENT!
