Access to page within a frame

I have the foll scenario:
a frameset (call it frame_top) that has 2 frames:
a.asp
b.asp
clicking a button a.asp submits the page to the same page which then redirects based on the action to another frameset page (call it frame_container) that again has two frames.
So now I have a frameset that in one fo the frame pages has another frameset that has 2 frames.
I want to access the elements in the top frame i.e. frame_top
fom one of the pages in frame_container

is that possible?
I have tried the foll:

1)parent.parent.frame_name_in_top_frame.document.form_name_in_top_frame.bid.value

2)parent.top..frame_name_in_top_frame.document.form_name_in_top_frame.bid.value


BUT nothing seems to work..

Any help on this would be greatly appreciated..

Thanks in advance!

Did you try

top.frame_name_in_top_frame.document.form_name_in_top_frame.bid.value
