Delete in database based on multiselect list values

Question

Hi,
I have a selectlist in Apex and a function in the database to do some delete based on the selected value from the select list.
FUNCTION delete_batch (v_batch VARCHAR2) RETURN VARCHAR2
IS
BEGIN
IF v_batch like 'M%'
THEN
   RETURN ('A monthrun cannot be deleted');
ELSE
   DELETE FROM so_disco_pa
   WHERE  batch = v_batch
   DELETE FROM so_batch_pa
   WHERE  batch = v_batch
   COMMIT;
   RETURN ('Batch '||v_batch||' has been deleted');
END IF;
EXCEPTION
WHEN OTHERS THEN
    RETURN ('Batch could not be deleted');
END delete_batch;The package function is called when the delete button is clicked with following process:
BEGIN
DECLARE
x   varchar2(100);
BEGIN
x := pa_control.delete_batch (:P3_BATCH);
:F105_MESSAGE := x;
END;
END;Now I want to change the selectlist to a multiselect list so that multiple batches can be deleted.
How do I change my procedure and process to delete batches based on the selected values?
Thanks,
Diana

I got this so far, but only the first batch selected in the list is being deleted. The other selected batch values are not deleted.
Some help please.
FUNCTION delete_batch (v_batch VARCHAR2) RETURN varchar2
IS
T Apex_application_global.vc_arr2;
BEGIN
T := apex_util.string_to_table(v_batch);
For I in 1..t.count loop
IF  t(i) like 'M%'
THEN
   RETURN ('A monthrun cannot be deleted');
ELSE
   DELETE FROM so_disco_pa
   WHERE  batch = t(i)
   DELETE FROM so_batch_pa
   WHERE  batch = t(i)
   COMMIT;
   RETURN ('Batch '||v_batch||' has been deleted');
END IF;
end loop;
EXCEPTION
WHEN OTHERS THEN
    RETURN ('Batch could not be deleted');
END delete_batch;
