[Koha] Regarding the overdue fines calculation

Dear All, Some of our library members overdue fines are not getting calculated by koha. We have also set the crontab which runs on daily basis. We are using koha 3.02 installed on opensuse 12 and facing below issue when i manually run the script of fines.pl *No branchcode argument to new. Should be C4::Calendar->new(branchcode => $branchcode) at fines.pl <http://fines.pl> line 135* Any help regarding the issue will be greatfull. Thanks in advance.
