Failed validation highlights entire column in tabular form

Question

Hi,
I have a tabular form where one of the field is a date field. I need to ensure that that the date selected or entered falls in the correct range of another page item P6_WEEK_ENDING. Here is my code.
DECLARE
     last_week_fri      DATE;
     this_week_fri     DATE;
     in_range NUMBER:=1;
     ret_bool BOOLEAN := TRUE;
BEGIN
     -- Get current end of week ID
     this_week_fri:= CONVERTDATE2(:P6_WEEK_ENDING);
     SELECT CONVERTDATE2(this_week_fri-7) INTO last_week_fri FROM DUAL;
     FOR i in 1..apex_application.g_f03.count LOOP
          IF apex_application.g_f03(i) IS NOT NULL THEN
               CASE
                    WHEN CONVERTDATE2(apex_application.g_f03(i)) >= CONVERTDATE2(last_week_fri) AND CONVERTDATE2(apex_application.g_f03(i)) <= CONVERTDATE2(this_week_fri) THEN
                         null;
                    ELSE
                         in_range:=0;                    
               END CASE;
          END IF;
          if in_range != 1 THEN
               ret_bool:= FALSE;
               EXIT;
          END IF;          
     END LOOP;
     return ret_bool;
END;Where
convertdate2 takes date format and outputs date in dd-mm-yyyy format.
apex_application.g_f03(i) is the date field.
Now it all works well except when my validation fails, it highlights the entire column instead of highlighting the only the bad entries.
I have my execution scope as : Created and Modified Rows, tried changing it with no luck.
Many thank.

Taepodong ,
I assume this is a validation. When you first created the validation, you either selected a page item or tabular form. If you selected the latter, you then selected the tabular form to which the validation would apply. On the next screen, you were asked to "Identify the validation level:" I am guessing that, at that point, you selected "Tabular Form Row" rather than "Column" The former will highlight the entire row, while the latter will only highlight the column which was specified.
