hi,  
i want a observe field to get which radio button has selected , i was  
tried , but i was returning both ids when clicked on one among two  
My View code looks like this:  
\<% fm.food\_item.food\_options.each do |option| %\>

\<%= option.food\_item.food\_name %\>
\<%= observe\_field("option.food\_item.id", :frequency =\> 0.5, :url =\> { :action =\> :modify\_subfood\_intake, :fm =\> option.food\_item.id, :date =\> date}, :with =\> "'sub\_food\_taken='+value") %\> \<% end %\> is it i should call observe field out side loop, then i dont get food\_item.id !!

any ideas  
thanks
