Rails - Jan 2006 - Rails newbie question

Ok, I''ve got an autocomplete dropdown, and what I want to do is get the
value selected from the dropdown, and then render a link_to that will 
pass that value (:id => ???) to a controller method. Can I do this all 
in the partial (like I''m attempting below), or do I have to go from 
text_field_with_auto_complete back to the controller, then render the 
link_to in another partial?

The dropdown part works fine, btw. I''m just having trouble accessing 
it''s value.

<%= text_field_with_auto_complete :patient, :name,
        {}, :skip_style => true,
        	:url => {:action => "auto_complete_for_patient_name",
        		      :cohort_id	=> @cohort_id
        		    }
%>

<%= link_to "add", { :controller => "foobar",
                     :action => "get_patient_info",
                     :id => ??? },
                     :class => "nav"
%>

Heeeellllllp!!!!!

thanks in advance,
Dave
