Hi,
This has nothing to do with Ceon Manual Card. This is code from a custom module you have installed.
Find out which module you have installed that uses a "balance due" field and fix it so that it works with standard Zen Cart payment modules.
Ceon Manual Card's use in this case is simply highlighting/showing you a problem caused by another module. Ceon Manual Card is not part of the problem.
Hope that helps!
Goof luck with your new store!
All the best...
