How do you populate right side of Shuttle control

Question

Hi,
I am trying to use shuttle control. I am not sure how to populate the right side of the shuttle control from database. I am using the following code. But, it is not populating the right side. In this code, P35_COUNTRIES is my shuttle. P35_X is a text field just to test the output. I can see an output 5:8:9 in the text field. But, my shuttle right side is empty. Am I doing something wrong here ? I would really appreciate any suggestions.
DECLARE
vCountries VARCHAR2(100);
vSEP VARCHAR2(1);
BEGIN
:P35_X := 'Inside test';
vCountries := '';
FOR C IN (SELECT country_id FROM countries WHERE territory_id = 1)
LOOP
vCountries := vCountries || vSEP || c.country_id;
:P35_X := vCountries;
vSEP := ':';
END LOOP;
:P35_COUNTRIES := vCountries;
:P35_X := vCountries;
END;
Thanks

Hi,
Yes, it is getting populated: [http://apex.oracle.com/pls/otn/f?p=30879:5]
My Source settings for the shuttle ("P5_SHUTTLE") are:
Source Used: Only...
Source Type: Static Assignment...
Source Value: (Blank)
Post Calc Computation: (Blank)
Default Value: (Blank)
List of Values Definition: SELECT DNAME d, DEPTNO r FROM DEPT ORDER BY 1
Settings for my Computation for this item:
Item Name: P5_SHUTTLE
Type: PL/SQL Function Body
Computation Point: Before Header
Computation:
DECLARE
vDEPT APEX_APPLICATION_GLOBAL.VC_ARR2;
i NUMBER := 1;
BEGIN
FOR c IN (SELECT DISTINCT DEPTNO FROM EMP WHERE ENAME LIKE 'A%')
LOOP
  vDEPT(i) := c.DEPTNO;
  i := i + 1;
END LOOP;
RETURN APEX_UTIL.TABLE_TO_STRING(vDEPT);
END;This computation is unconditional, so runs everytime the page is loaded.
