Hi,

I think your problem is this line:
@g=3DGroup.find_by_group_name(params[:group_name]).id

you want to pass the params :group_name which are nil because in your =
form you don't pass the :group_name to your controller:

<% form_tag (:controller =3D> "users" , :action =3D> =
"addfriendtogroups")
do %>

       Add friend:
        <%=3D text_field_with_auto_complete :user, 'login', {:size =3D>
20}, {:tokens =3D> ','} %>

           <%=3D submit_tag "Add to group", :class =3D>
"submit_input_button rounded_corner" %>
<% end %>

So pass your :group_name trough a hidden field to your controller

hidden_field=20
