I've embedded a Google Map into a pop-up aspx page but am having trouble reading the co-ords from the parent page's form. I keep getting a 'window.opener.document.getElementById(...)' is null or not an object.. Any ideas?
The line it errors on in the pop-up is:
window.opener.document.getElementById('intZoom').v alue = document.getElementById('iZoom').value;
Form element ID on parent page is intZoom, and iZoom in pop-up. I'm using IE 7.0.5730.13
Any help greatly appreciated..
