I have two frames, the top one has a select box with a few different values, based on the selection I want to trigger an onchange event that forces the bottom frame to reload a different page for each selection, I have tried passing a querystring but you can not do a redirect once the header has been built. Any ideas. I need to keep the bottom pages on the same page as the top frame, but alter the different forms based on the selection. I would appreciate any advice.
