Starting with Triggers

Hello,
I have never writen a trigger before and need some advice. I have two tables and when data is inserted into table A then I need to insert the same data into table B along with the time.

create or replace trigger shadowDepts
after insert on depts
begin
insert into depts_shadow values(deptno,dname,sysdate)
end;
/

except deptno and dname are the values of what was inserted into the original Table A.
How do I access those values... I tried using ":new" but it gave me an error, I think because it is not a "for each row" trigger.

Please let me know where I am going wrong,
Thanks,
Ryan

try that:

create or replace trigger shadowDepts
after insert on depts
for each row
begin
insert into depts_shadow values(:new.deptno,:new.dname,sysdate);
end;
