Hi
I have installed the latest build version 4.
Everything is working fine till I add tax on the menu and also use the calculation type round to set up an additional charge for room service. However when I press the cash button the application crashes with the error below. Kindly tell me what is it that im doing wrong and what is the right was to configure extra charge on room service.
Update: After I removed the TAX, everything is working normal. So then what am I doing wrong and how to add tax?
