Thank you for your interest! I'm sorry to hear this isn't working for you. What version of Cha-Ching are you using? There was a database change in 1.04 that this script is designed to work with. So if you are using a previous version, that is probably the reason for the issue.
Please let me know if I can be of further assistance, and feel free to email support@hungryturtle.com with more information if you need to.
(Version 1.1)
