How to update table in for loop with disturbing existing values

Hi,

I have one table with some values as shown in below format...
Column-A Column-B Column-C Column-D Column-E
11AA ------ 1234 ------ ASDF------ FIRST ------ONE
22BB ------ 2345 ------ WSDF------
33CC ------ 3456 ------ YES ------
44DD ------ 4567------ NO -----
55EE------ 5678 ------ DUP ------ SECOND -----TWO
66FF------ 6789 ------ OK------

In order to update, i have GUI which is displaying the above table...
Now i want to update Column-D & Column-E of second row....
For that i have written code as......written below----

For i IN 1..Column-D.LENGTH LOOP

UPDATE table
SET Column-D = THIRD(value1 from GUI) AND
Colun-E = THREE(value2 from GUI)
WHERE Column-A= '22BB'

END LOOP;

But it is not updating proplerly...
IT is showing output as

Column-A Column-B Column-C Column-D Column-E
11AA 1234 ASDF THIRD THREE
22BB 2345 WSDF
33CC 3456 YES
44DD 4567 NO
