Returning clause issue

Question

drop table mytest
create table mytest(sid number, sname varchar2(40),source_id number, flag varchar2(1));
insert into mytest (SNAME,SOURCE_ID, FLAG) values ('kd',null,null);
insert into mytest (SNAME,SOURCE_ID,FLAG) values ('kd',null,null);
commit;
create sequence seq_t
start with 1
increment by 1
CREATE OR REPLACE TRIGGER TBIU_MYTEST
BEFORE INSERT OR UPDATE ON MYTEST
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
IF inserting THEN
IF :new.SID IS NULL THEN
SELECT SEQ_T.NEXTVAL
INTO :new.SID
FROM DUAL;
END IF ;
END IF ;
END ;
I wrote a procedure, given an sid, we create new record with source_id will be stored as sid (input param) and flag is Y,
But I want to see the new sid in the output param using returning
CREATE OR REPLACE PROCEDURE copy_sid
( in_sid IN mytest.sid%TYPE, out_sid OUT mytest.sid%type
IS
BEGIN
INSERT INTO mytest (sname, source_id, flag)
SELECT sname, sid, 'Y'
FROM MYTEST
WHERE sid = in_sid
returning sid into out_sid;
END copy_sid;
what is wrong with above syntax ? it gives command not
propely ended in the returning cluase
