TOPIC: way to stop a registration with a bad discount code

Have an issue with, well to put in bluntly, dumb users. they try to over use a code and while the screen warns them that code is bad they press on with the registration and wind up with wrong amount etc and then we have to fix/refund and straighten out mess.

Soo is there a way to not let the registration continue with a bad discount code (no code is fine of course). possible just by removing the "next step" button when the warning message is present?

thax and would appreciate any ideas

There is no present way to disable registration without a good discount code. We'll try to work something like that in.
