I am facing some problem while develoing a data block in a form.

Details are below,
        001   ABC         35      35     35     20
        002   DEF         40      39     52     25
        003   GHI         35      41     49     20
        004   JKL         36      35     50     30

My data block contains all the records from the STUDENT table.
Now I want in Modify operation that user are not allowed to change the values of TEST1,TEST2 and TEST3 columns for with the all three values are 35, but allowed to change value of GRACE of the same.
User shuld be able to change all the four column for other values of TESTn columns.
When I tried to write item level code in POST-QUERY trigger, it is changing the status for all the record instead only for records which have TESTn column values equal to 35.

Waiting for reply.

use When-New-Item-Instance trigger with set_item_instance_property as suggested by "cookiemonster"

In the trigger write this code
if :STUDENT.TEST1 = '35' then
   set_item_instance_property('STUDENT.TEST1', current_record, update_allowed, property_false);
end if;

Write this code on TEST2 and TEST3 as well.
