Current: All types of customer data entered have not been tested. That is the 3rd step (including the Custom Feild). Specifically: The phone number must be entered in full, so it is correct, but the current full junk characters, still allowed. Address: Enter a serial number, still allowed. Or post number: Type Full characters are still allowed to send. Bookly's programmers did not rigorously examine the data types of the libraries. Please correct and update for customer.
