document.form.field.value is null or not an object

Hi,
I am getting the document.form.field.value is null or not an object when i am trying to do the following,


function submitTrackRequest(url,dno,courierTo){
if(courierTo == 'DHL'){
document.frmTrackByNbr.txtTrackNbrs.value=dno;
document.frmTrackByNbr.action=url;
//alert(url);
document.frmTrackByNbr.target="_child";
document.frmTrackByNbr.submit();
}else{
document.frmTrackByNbr.tracknum.value =dno;
url=url+dno;
//alert(url);
document.frmTrackByNbr.action=url document.frmTrackByNbr.target="_child";
document.frmTrackByNbr.submit();
}




<% String name="txtTrackNbrs"; %>


.
.
.
.
','<%=arrtrack[k]%>','<%=arrcourierTo[k]%>');">


So when the above link is clicked the values are passed to the javascript and it should open other url as passed in the calling function.

When i click this link in the front end(IE) i am getting the javascript error "document.frmTrackByNbr.tracknum is null or not an object error"

Can anyone help me resolve this issue.

Thanks
ri
