Error in Dynamic Value Change Using Java script

Question

Hi ,
I am trying to put dynamic value sin tabular form report.
I used the below code
function updateLOV3(filter, listName,itemId,po_no){
var xml = null;
var list = document.getElementById(listName);
  var get = new htmldb_Get(null,$v('pFlowId'), 'APPLICATION_PROCESS=Update_Invoice_UOM',0);
alert(po_no);
alert(itemId);
get.add('TEMPORARY_ITEM', po_no);
get.add('TEMP_ITEM', itemId);
alert(list);
ret = get.get('XML');
if(ret){
  var s = ret.getElementsByTagName("select");
  if(s){
   var o = ret.getElementsByTagName("option");
   oCount = o.length;
   if(oCount!='0'){
        var l_Opt_Xml = o[0];
        appendToSelect(list, l_Opt_Xml.firstChild.nodeValue);
if(oCount=='0'){
alert('entering');
   list.value=0;
get = null;
function appendToSelect(pSelect,pContent) {
alert(pContent);
pSelect.value=pContent;
}my Application Process code is
declare
begin
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
htp.prn('<data>');
htp.prn('<select>');
for rec in (SELECT UNIT_OF_MEASURE r ,UNIT_OF_MEASURE d FROM HOMES_RGP_PURCHASE_ORDER_LINES WHERE ITEM_ID = :TEMP_ITEM AND
PURCHASE_ORDER_ID = :TEMPORARY_ITEM)
loop
htp.prn('<option value="' || rec.d || '">' || rec.r || '</option>');
end loop;
htp.prn('</select>');
htp.prn('</data>');
end;In my application process if i removed the PURCHASE_ORDER_ID = :TEMPORARY_ITEM then the value is coming.
Java Script giving both values like item id and purchase order id.
If i ran the sql query manually its giving values.
i hope thers is some error in get.add method in java script.
Its always going into the below condition
if(oCount=='0'){
alert('entering');
   list.value=0;
get = null;but manually i have checked the database the value is present.
Please anyone help me out in this.

Hi all,
The same i have checked with emp table but still i got the same problem.
Its my application process
declare
begin
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
htp.prn('<data>');
htp.prn('<select>');
for rec in (SELECT ename r,ename d FROM 
emp
WHERE  empno = :TEMP_ITEM)
loop
htp.prn('<option value="' || rec.d || '">' || rec.r || '</option>');
end loop;
htp.prn('</select>');
htp.prn('</data>');
end;My Javascript code is
<script type="text/javascript">
function setvalues(itemId,list)
var s = $v(itemId);
alert(s);
var get = new htmldb_Get(null,$v('pFlowId'), 'APPLICATION_PROCESS=POPULATE_EMPNAME',0);
get.add('TEMP_ITEM', s);
ret = get.get('XML');
if(ret){
  var s = ret.getElementsByTagName("select");
  if(s){
   var o = ret.getElementsByTagName("option");
   oCount = o.length;
   if(oCount!='0'){
        var l_Opt_Xml = o[0];
        appendToSelect(list, l_Opt_Xml.firstChild.nodeValue);
if(oCount=='0'){
   list.value=0;
get = null;
function appendToSelect(pSelect,pContent) {
pSelect.value=pContent;
</script>Can anyone suggest me what i have missed???
