How can i creat a trigger error invalid trigger specification

Question

i have a stored procedure which i want it to be triggered when an insertion is done on table A
and that stored procedure accepts values from the insertion performed in table A
and inserts into Table B by either updating the table or insertion into Table B
how can i achieve this
OK fine i have a table called Table A
i want a trigger that can accept values such as
create or replace trigger UpdateMyDoc  after insert on  Table A
for each row
accoutntno varchar2,
ID varchar2
As
cnt number;
Begin
update Table B value (accoutntno ,ID ); commit;
end ;
is the above possible if it is then i get this  [1]: (Error): ORA-04079: invalid trigger specification
any help

Answer 1

Stop right there, Kama.
update Table B value (accoutntno ,ID ); commit;Do not go any further on triggers, until you at least know how to write an UPDATE
Or is it INSERT
Once you have that in place, carry on by reading a bit about Transactions
