I am trying to add a new item to an asp listbox using javascript from a child window.  I have tried the following code on my child page without any luck:

var to = window.opener.document.getElementById("Recipient");
     to.options.add(new Option('1','1'));


I have also tried:
var to = parent.document.getElementById("Recipient");
without any luck also.

The following code works fine on the parent page to add new items to the listbox:
   
function AddItem(){
    var to = document.getElementById("Recipient");    
     to.options.add(new Option('1','1'));
     }

Any help is greatly appreciated.

try

alert(window.opener)

and verify that it doesn't say "null" if it does there's something wrong with how you're accessing the child window.

The javascript error returned when I run the script mentioned in my question is:

"Error: Unspecified error."

Not too useful...  :-)

And this still results in an error?

var opt = new Option('1', '1');
window.opener.document.getElementById("Recipient").options.add(opt);

If that doesn't work try this. Add this function to the child page:

function AddItem(opt){
    var to = document.getElementById("Recipient");    
     to.options.add(opt);
}

And then on the main page try this:

window.opener.AddItem(opt);

Now I receive the "Unspecified error" on the parent page when AddItem is called.

Very weird, but I got this working:

On Parent Page:

    function AddItem(Recipient){
    alert(Recipient);
    var to = document.getElementById("Recipient");    
    to.options.add(new Option(Recipient,Recipient));
     }

On Child Page

    function addRecipient(RecipientName){              
    window.opener.AddItem(RecipientName);
    }
