Cursor within cursor insert problem.

Question

Hello,
Am trying to pass a parameter from one cursor to another and making an insert in the 2nd cursor but its not inserting.
declare
v_txt_1 varchar2(10);
v_txt_2 varchar2(10);
cursor C1 is
select txt1,txt2 from test1where country='INI';
cursor C2(p_txt_1 varchar2,p_txt_2 varchar2) is
select txt1,txt2 from test2
where old_cat_1=p_txt_1
and old_cat_2=p_txt_2;
begin
for c1rec in c1 loop
v_cat_1 := 'AA';
v_cat_2 := 'BB';
v_cat_3 := 'CC';
for c2rec in c2(c1rec.cat_1,c1rec.cat_2,c1rec.cat_3) loop
insert into chnl_ini_test (new_cat_1,new_cat_2,new_cat_3,remarks) values (v_cat_1,v_cat_2,v_cat_3,'CATEGORY not found');
end loop;
end loop;
end;
END;
the block gets executed but the insert is not happening. am not getting any error. if I place the insert below the first for loop then the insertion is happening.
Any suggestions plz.

Looking at the example code, it seems that the values to be INSERTED are not taken from the cursor.
Instead we just want to insert the same values multiple times based on the no. of rows returned from the cursor c2 and c1.
If that is the case :
* Query for both cursor c1 and c2 can be Merged.
* Count the no. of rows returned.
* Use FORALL to insert all the records in one shot.
DECLARE
    v_txt_1 VARCHAR2(10);
    v_txt_2 VARCHAR2(10);
    w_count PLS_INTEGER;
BEGIN
    SELECT
        COUNT(*)
    INTO
        w_count
    FROM
            SELECT
                t2.txt1,
                t1.txt2
            FROM
                test2 t2,
                test1 t1
            WHERE
                country  ='INI'
            AND old_cat_1=t1.txt1
            AND old_cat_2=t2.txt2
    v_cat_1  := 'AA';
    v_cat_2  := 'BB';
    v_cat_3  := 'CC';
    FORALL i IN 1 .. w_count
        INSERT
        INTO
            chnl_ini_test
                new_cat_1,
                new_cat_2,
                new_cat_3,
                remarks
            VALUES
                v_cat_1,
                v_cat_2,
                v_cat_3,
                'CATEGORY not found'
END;
