Insert/update - merge apex items

Question

hello =)
i want to insert data into a table and if the table has already the "List_id" i want to update values:
begin
FOR i IN 1..APEX_APPLICATION.G_F01.COUNT LOOP
MERGE INTO list_values
USING dual
ON (list_values.list_id = to_number(APEX_APPLICATION.G_F02(i))
WHEN MATCHED THEN
UPDATE
SET
list_values.product_fk=:P900_PRODUCT_NAME,
ist_values.attribute=APEX_APPLICATION.G_F04(i),
list_values.value=APEX_APPLICATION.G_F05(i)
WHEN NOT MATCHED THEN
INSERT
list_values.product_fk,list_values.attribute,list_values.value
VALUES
*:P900_PRODUCT_NAME,APEX_APPLICATION.G_F04(i),APEX_APPLICATION.G_F05(i)*
end loop;
end;
got a lot of sql errors...
+1+ error has occurred
ORA-06550:line 6, column 65: PL/SQL: ORA-00907: missing right parenthesis ORA-06550: line 4, column 1: PL/SQL: SQL Statement ignored
Maybe someone can help me with the syntax of the merge statement or maybe merge doesn't work in this case. because of the apex_items.
also got seperated insert/update process. they work perfect, if i use the processes singly:
Begin
FOR i IN 1..APEX_APPLICATION.G_F01.COUNT LOOP
insert into List_values (product_fk,attribute,value)
values (:P900_PRODUCT_NAME,APEX_APPLICATION.G_F04(i),APEX_APPLICATION.G_F05(i));
END LOOP;
end;
begin
FOR i IN 1..APEX_APPLICATION.G_F01.COUNT LOOP
update List_values
set
product_fk=:P900_PRODUCT_NAME,
attribute=APEX_APPLICATION.G_F04(i),
value=APEX_APPLICATION.G_F05(i)
where list_id=to_number(APEX_APPLICATION.G_F02(i));
END LOOP;
end;
Maybe someone can help me to combine them.
Thank u =)

You were missing a right parenthesis at the end of line 7.
BEGIN
   FOR i IN 1 .. APEX_APPLICATION.g_f01.COUNT
   LOOP
      MERGE INTO LIST_VALUES
           USING DUAL
              ON (LIST_VALUES.list_id =
                     TO_NUMBER (APEX_APPLICATION.g_f02 (i)))
      WHEN MATCHED
      THEN
         UPDATE SET
            LIST_VALUES.product_fk = :p900_product_name,
            ist_values.attribute = APEX_APPLICATION.g_f04 (i),
            LIST_VALUES.VALUE = APEX_APPLICATION.g_f05 (i)
      WHEN NOT MATCHED
      THEN
         INSERT     (LIST_VALUES.product_fk,
                     LIST_VALUES.attribute,
                     LIST_VALUES.VALUE)
             VALUES (
                       :p900_product_name,
                       APEX_APPLICATION.g_f04 (i),
                       APEX_APPLICATION.g_f05 (i));
   END LOOP;
END;Jeff
