Select box selected on value ? w option_for_select

Rails
1

I have a select box in my view, with an option for select, a variable
for selected value, and an Ajax observe_field


<%= options_for_select({ “most cheerful” => “1”, “most beautiful” =>
“2”, “most displayed” => “3”}, @sort_criteria) %>

    <%= observe_field("most_criteria",
          :update => "results_table",
          :url => { :action => :list , :params =>

@params.merge({:page=> nil })},
:with => “‘sort=’+value”,
:on => “changed”)
%>

when changed I get the params[:sort] set to the seelcted value…
but setting @sort_criteria to params[:sort] doesn’t select anything at
all…
what’s the correct params to be set ?

tfyh
