Validate form elements on checkout page
I have been searching and reckon this thread is the closest to what I need!
I want to validate the credit card and billing address fields in checkout.asp (created by the eCart wizard). I applied server side validation to the confirm.asp page and it works brilliantly. My only problem is that I am returned to the checkout.asp page (quite correctly) but I can't work out how to display an error message on that page to the user. Is this possible?
