I did try typing in the new amount. That's when I got the message “you have already printed a bill using this bill arrangement. You can click Amount Calculator to re-calculate the amount of this bill arrangement or click Start Another Flat Fee to complete the current bill arrangement and start a new one.” The thing is, the definition says you can change the fee as long as you haven't exceed the flat fee amount (which, by the way, how could you?)
