Forms within forms?

[Doug Nebert]

I have been experimenting with continued success in adding 
layers to be viewed via the mapimage applet with the controls 
and reference map displayed alongside in HTML. The communication 
between the HTML and the mapserver seems to be done with 
JavaScript within a form. Thus a redraw map request is a form 
action. 

This is all very nice if that is the only event I want to do, 
but I have the need to use the resulting coordinates from the 
current window (the search rectangle, not the map extent) and 
pass them to another process to do search with. It first 
seems that I would need more than one form to do this but I 
am lost as to how this is done or what alternatives there would 
be, other than folding all the functions inside the applet. 

Example solutions, please!
