I have a web application using coldfusion and mysql. There is a form where
customer's payment is entered and submitted. Upon submission customer's
balance is updated. Sometimes customer's balance is updated twice.
How do I prevent this from happening?  

Example:
Balance:  1000
payment: 100
After update: balance = 800
 
Thanks.
