window.opener not working

[GWINTO]

I am trying to reset a select box in a parent window without refreshing the whole page, the child window is used to enter a new value for a drop down box.
The function that should work is:
function refreshlist(passedid)
{
alert(passedid);
var thebox=window.opener.getElementById(passedid);
alert(thebox.id)
thebox.options[thebox.options.length] = new Option('<%=idvalue & &quot;','&quot; & showValue %>');
alert(thebox.options.length)
window.close();
}

The alert boxes are for debugging.

The function is executed using <a href etc> from a child window that is opened from the parent.

The first alert box appears Ok with the correct value, then nothing happens.

Alert(window.opener.value), returns 'unspecified'
Alert(window.opener.location), returns the URL for the child window
Alert(document.parentWindow.location), returns the URL of the parent window

Alert(window.opener.location), returns the URL for the child window

Really?? Should be the URL of the page that opened the window...

Sorry got the last 2 the wrong way round should have been:

Alert(window.opener.location), returns the URL of the parent window
Alert (document.parentWindow.location), returns the URL for the child window

Did this help?

var thebox=window.opener.document.getElementById(passedid);

var thebox=eval(&quot;window.opener.document.form.&quot; + passedid);
