you iframe does not have an opener, the page containing it does, so you
want window.parent.opener (or however deep you are).
as showModalDialog is now w3c complaint it a bad practice to start using
it. now days this is usally done with a floating div (sometimes
containing an iframe). usually the div is dislayed, and the background
page is gray'd out. there are a lot of sample modal dialogs that work
this way. there are several for jQuery and the ajax toolkit has one.
