Hi Morten,
I am sorry for not getting to this sooner. The error message tells you that the CashBookHandle is null. I don't know if that could be because of the casing. Try changing the lower case c to an uppercase C.
You can find a list of available CashBooks by calling CashBook_GetAll.
If you keep getting this error, then contact us at api@e-conomic.com
