Hello!
I am currently trialling SambaPOS. My main initial aim is to get a lot of the standard features of a hospitality system such as fast user switching, user security controls for discounts etc.
It had been going okay but I realised I would need a ‘food discount’ button. To facilitate this I used a file from the post Checkbox for a product item to exclude it from "discount %" calculation
Unfortunately, after I load this and go into the POS, the POS throws up an exception as soon as I try and sell something.
Naturally I can restore to the backup but just wondered if anyone had any ideas?
I tried resetting the database and reloading the file mentioned. After I log back in, do a ‘start work period’ and try and sell something, same exception occurs.
The exception details are below.
