Hi Jones,
Looks like a problem with you table using a reserved word. Look at this example using DATE as column name:
10gR2>create table petty_cash ("ID" number, "DATE" date);
Table created.
10gR2>create sequence se_petty_cash;
Sequence created.
10gR2>create or replace trigger petty_cash_trggg
  2     before insert
  3     on petty_cash
  4     referencing new as new old as old
  5     for each row
  6  begin
  7     select se_petty_cash.nextval
  8       into :new.id
  9       from dual;
10  end;
11  /
   on petty_cash
ERROR at line 3:
ORA-06552: PL/SQL: Compilation unit analysis terminated
ORA-06553: PLS-320: the declaration of the type of this expression is
incomplete or malformed
10gR2>drop table petty_cash purge;
Table dropped.
10gR2>-- Create table without use of double quotes
10gR2>create table petty_cash (ID number, DATE date);
create table petty_cash (ID number, DATE date)
ERROR at line 1:
ORA-00904: : invalid identifier
10gR2>-- That forces me not to use reserved word
10gR2>create table petty_cash (ID number, MY_DATE date);
Table created.
10gR2>create or replace trigger petty_cash_trggg
  2     before insert
  3     on petty_cash
  4     referencing new as new old as old
  5     for each row
  6  begin
  7     select se_petty_cash.nextval
  8       into :new.id
  9       from dual;
10  end;
11  /
Trigger created.Regards
Peter
