Asp.NET调用存储过程报PLS-00201: identifier must be declared错误的问题

[双木宝宝]

存储过程源码：

create or replace package body pk_erp_w
as
procedure ElectricityAmountPoor(v_date1 varchar2,v_date2 varchar2,cur_return out cur_result)
  as
  
  begin

  open cur_return for
  select sum(t3.vamount) as vamount,
       t3.position,
       t3.elename,
       t3.devicename,
       t3.opertypename
  from (select t1.instrumentid,
               t1.vamount,
               t2.instrumentname,
               t2.opertypename,
               t2.devicename,
               t2.elename,
               t2.position
          from (select t.instrumentid, sum(t.vamount) as vamount

  EXCEPTION
    WHEN OTHERS THEN
      ROLLBACK;
      DBMS_OUTPUT.put_line(SQLERRM);
      return;
end ElectricityAmountPoor;

求大神看看哪里有错误。谢谢！
