Apex 4.0 Collection Error

Question

Hello All
I have a report created on collection here is the code:
On Fetch Process before header:
if NOT APEX_COLLECTION.COLLECTION_EXISTS (p_collection_name => 'EMP' ) then
APEX_COLLECTION.create_collection(
p_collection_name => 'EMP');
EXECUTE IMMEDIATE 'SELECT COUNT(EMP_ID) FROM '||:FY_SCHEMA||'.EMPLOYEE WHERE COMP_ID = '|| :P152_COMP_ID INTO emp_cnt;
FOR i IN 1 .. emp_cnt
loop
APEX_COLLECTION.ADD_MEMBER(
p_collection_name => 'EMP',
p_c001 => i);     
end loop;
apex_collection.reset_collection_changed ('EMP');
end if;
Report Query:
SELECT SEQ_ID,c001, c002 FROM APEX_COLLECTIONS WHERE COLLECTION_NAME = 'EMP'
From one of the column in this report I am calling a javascript function where I am doing to sum of that column.
It works fine when there are more than one rows, but when there is only one row it is not calculating the total of the column.
After doing some R & D, I found that, in case of one row the length of wwv_folw.f01 item is coming as undefined(see the comment in js code).
Here is my javascript function:
function total_sal(){
pRow = 1;
var total = 0;
var salary;
var i;
var val1;
alert(document.wwv_flow.f01.length); *// here it is showing undefined in the popup*
for(i=0;i<document.wwv_flow.f01.length;i++){
salary = document.wwv_flow.f03.value;
if(salary != ''){
total = total + parseInt(salary);
else{
break;
document.getElementById('P152_TOTAL').value = total;
Please tell me where I am going wrong
I have one more question with regards to interactive report,
I have given format mask for some columns from edit columns, but it is not showing in that format at the front end.
Is there any other way for that?
Thanks

Hi,
wwv_flow is pl/sql package and I think you can not use it in javascript.
You can do something like
function alertF3(){
var f1=new Array();
var f3=new Array();
f1=document.getElementsByName("f01")
f3=document.getElementsByName("f03")
for(i=0;i<f1.length;i++){
  alert(f3.value)

Sorry, wwv_flow is also form name so this should work alsofunction alertF3(){
var f1=new Array();
var f3=new Array();
f1=document.wwv_flow.f01;
f3=document.wwv_flow.f03;
for(i=0;i<f1.length;i++){
alert(f3[i].value)
