Working in Sql, not working in Stored procedure

Question

Dear friends,
I am puzzled about this strange working of Oracle , although I know that there is some problem with my code. I paste my code here. The delete statement is working properly in SQL Plus 8.0, but it is not working when I call this stored procedure from the Form.
FUNCTION delete_record_treaty (
p_treaty_id T_RIN_TREATY_MST.TRTY_ID_GV%TYPE, p_value VARCHAR2,p_block VARCHAR2 )
RETURN BOOLEAN IS
v_treaty_type varchar2(5);
BEGIN
v_treaty_type := substr(p_treaty_id,1,3);
if p_block !='T_RIN_GRP_DTL' and p_block != 'T_RIN_XOLSLAB_DTL' and p_block!='T_RIN_PMTSCHD_DTL' then
delete from T_RIN_TREATY_MST where TRTY_ID_GV=p_treaty_id ;
commit;
end if;
if v_treaty_type = 'QTA' then
delete from T_RIN_GRP_DTL where TRTY_ID_MV=p_treaty_id and T_RIN_GRP_DTL.ROWID = p_value;
commit;
elsif v_treaty_type = 'XOL' then
delete from T_RIN_XOLSLAB_DTL where TRTY_ID_MV=p_treaty_id ;
delete from T_RIN_PMTSCHD_DTL where TRTY_ID_MV=p_treaty_id ;
elsif v_treaty_type = 'FAC' then
delete from T_RIN_PMTSCHD_DTL where TRTY_ID_MV=p_treaty_id ;
end if;
RETURN(TRUE);
END delete_record_treaty;
Thanks in advance.
All the paramaters that I pass, are correctly being passed to this stored procedure.
null

Answer 1

I solved it.One parameter I was passing it wrongly.
