It's all in a password protected site because the data's all confidential at
this point in time, but I can give you a mental picture.  

There are a bunch of dropdowns - State, Cancer, Sex, Race, Age.  We're
drawing a graph of best fit lines - up to 5 allowed on the graph, then we
start over replacing them.  We don't draw the actual data points unless the
user clicks on a checkbox.  They want that checkbox to be instant
gratification, without making the user refresh.  I just want a way to make
it do the refresh (and let me change that one variable, so it draws the
points or doesn't draw the points), but not a full submit because that would
add another line to the graph.

I'm sorry I can't send you the URL at this stage of the game.  it should be
up and running this summer though :-)

Thanks for any help you can give me!!

You wouldn't happen to have a demo would you? A visualization would help me
a lot.
