need help to do two-column transfer like [url]this image

I'm currently using this code on [ -> ] button:
     total_list_count          NUMBER(2);
     loop_index_var          NUMBER(2) := 1;
     list_element          VARCHAR2(50);
     list_element_to_add     VARCHAR2(50):=:Column1; --#Column One
     element_match          VARCHAR2(5) := 'TRUE';
     list_id                    VARCHAR2(5) := 'Column2';--#Column Two
     ** Determine the total number of list elements.
     total_list_count := Get_List_Element_Count(list_id);
     ** Compare the current list item elements with the element that
     ** will be added.
          list_element := Get_List_Element_Value(list_id,loop_index_var);

          IF list_element_to_add = list_element THEN
               element_match := 'FALSE';
          END IF;
          EXIT WHEN list_element = list_element_to_add OR     loop_index_var = total_list_count;
          loop_index_var := loop_index_var + 1;
          END LOOP;
     ** Add the element and value if it is not in the current list
     IF element_match = 'TRUE' THEN
          Add_List_Element(list_id, loop_index_var, list_element_to_add,list_element_to_add);
          --# DELETE ELEMENT FROM Column1
     END IF;
I'm facing problem in DELETE ELEMENT FROM Column1 (How to delete the currently selected element from the list?)
