Rails - Jun 2006 - retrieving parameter or selected value using remote_function

Hi,

  Can anyone let me know how to fetch selected option from the following 
select box :

<%= select(:category_view,:name,@categories_choices, {:include_blank => 
false},
{:onChange =>remote_function(:update => "div_team_coverage",
:url =>
{:action => :set_team_values} ,:with => "category="+
escape(value))} )
%>

<div id="div_team_coverage">
    <%= render(:partial => "team_coverage_data")%>
</div>

And I want to know how can I access this in the controller. When I try 
to access in controller as :

params[:category_view][:name]

I got nil params exception.

As i need it eagerly to fetch the value selected on first select box, 
and base on that i need to populate data in the second select box from 
the database.

Thanks in advance.
Joshua
