Range-List Composite partitioning table

I am trying to create Range-List Composite partitioning table.

I am getting the following error:

inv_num            char(8) not null,
bill_year      varchar2(4),
bill_month      number(2),
trans_title_key      number(20),
sales_units      number,
sales_dollars      number,
return_units      number,
return_dollars      number)
partition by range (bill_year)
subpartition by list(bill_month)
subpartition template(
subpartition jfm values(1,2,3),
subpartition amj values(4,5,6),
subpartition jas values(7,8,9),
subpartition ond values(10,11,12))
(partition y2001 values less than('2001'),

partition y2001 values less than('2003'),
partition y2001 values less than('2004'),
