The check_box helper doesn't take an :onchange option.  You want to use
observe_field to watch the check_box status.

You want to use :onclick. I have the same code (well, almost) in one of 
my apps. The only difference is that my remote_function call's value is 
placed within a variable:

<% func1 = remote_function(:url => {:action => "find2"}, :with => "'id=#
   {mercado.id}'") %>
<%= check_box "mercado", "nombre", {:value=>mercado.id, 
:name=>mercado.nombre},
   :onclick => func1 %>

Shandy, Fred;

Thanks!  I never knew we could use remote_function this way.  Learning
something new every day!
