POST-CHANGE TRIGGER

Question

Hi,
I am using Forms Version 9.0.4.0.19.
I created a form which consists of two blocks. Both blocks have a database field called city_code. I am trying to create a post-change trigger that would display the description and not the code of the city. Unfortunately, I keep getting no records found when I run the form although I now for certain there are records, there are records when I remove both triggers.
Here is my code for the trigger for block1:
=======================================================
BEGIN
     SELECT DESCRIPTION
     INTO :INST.txtCITY
     FROM DICT
     WHERE CODE = :INST.CITY_CODE
END;
=======================================================
Here is my code for the trigger for block2:
=======================================================
BEGIN
     SELECT DESCRIPTION
     INTO :CONTACT.txtCITY
     FROM DICT
     WHERE CODE = :CONTACT.CITY_CODE
END;
=======================================================
Thanks in advance.

Hi Again,
I thought it worked, it didn't give me an error when I compiled it, but when I ran the form the data didn't appear. Below is my code, can somebody please help?
DECLARE
     CURSOR LOOKUP_INST_TYPE IS SELECT DICT.DESCRIPTION
     FROM DICT
     WHERE DICT.CODE = :INSTITUTION.INST_TYPE
     AND DICT.TOPIC = 'INST_TYPE';
BEGIN
     OPEN LOOKUP_INST_TYPE;
     FETCH LOOKUP_INST_TYPE INTO :INSTITUTION.TXTINST_TYPE;
     CLOSE LOOKUP_INST_TYPE;
END;
