Say I have a page with 4 frames: header, list, content and footer

Using webclass I want to do this:
If a user click a button or link in the header frame, I want to update all other frames with new information.

I can't seem to get the webclass write into the correct frames. I tried a few option but what I get is either all content is written into one frame (the header frame since the event was triggered from that frame), or the header frame gets divided again into the four frames (it become frames in frame).

I tried specifying the target frame within the hyperlink but this will only work for updating that one frame, not all three. So I guess I need to do this (specifying the target) from code.

Anyone know how to do this??
