Hi All,
I have installed nibblebill and it is able to bill the calls.
However, it is  giving  following error in FreeSwitch server.

2009-03-17 23:17:19 [DEBUG] mod_nibblebill.c:283 bill_event() Doing update query
[UPDATE accounts SET cash=cash-0.045767 WHERE id="1"]
2009-03-17 23:17:19 [CRIT] mod_nibblebill.c:286 bill_event() DB Error while updating cash!

Thanks
