Question

I am using a frameset doctype on my page and also use js on that page..

I get the error window.TopFrame is null error...what does that mean?

Also any reference to how to refer parent/child modal windows correctly?

Answer 1

Try

window.top

to refer to the top-most window frame, and

window.parent

to refer to the parent of the current window.
