hi,  
I have the following problem:

**product.controller.rb**

def show  
…  
end

end

**show.html.rb**   
.  
.  
\<% Product.find (: all). each do | product|  
\<% = Check\_box “product”, “name”,: checked =\> false,: onchange =\>  
"# (remote\_function (: url =\> (: controller =\> ‘product’,: action =\>  
‘show’) )) "%\>   
  
\<% End%\>  
how can i get all the selected checkbox in the show-action(controller)?
