select_tag inside loop

I have a user who has a list of friends on displayed on his webpage. He can add each friend to a group like, Family or Friends. To implement this , I have the select_tag /form_tag block inside a loop in my view as shown:

<% @user.friend.each do |friend| %>         <%= form_tag({:controller => 'friendship', :action => 'addgroup', :id => friend.screen_name} ) %>   <%= select_tag( "groupname", options_for_select(%w{ Family Friends })) %>     <%= submit_tag "Add #{friend.name}" %>      <% end %> <% end %>

On submit the controller friendship/addgroup is invoked with parameter :id => friend.screen_name. I also access params[:groupname] in addgroup. My problem is that even though this is in a loop, when I click on "Add friend" and submit the form the :id => screen_name is always the first friend for the user in the database. What am I doing wrong ? Thanks

Doesn't submitting a form, submit all the params on the page, regardless of which form they're in? I'm probably wrong on that though.

Try distinguishing the forms by giving them differing names. Eg

  <%= form_tag({:controller => 'friendship', :action => 'addgroup', :id => friend.screen_name}, :name => "addgroup_form_#{friend.id}" ) %>
