Help with looping through groups of radio buttons

So my goal is to loop through and list several groups of shipping options for various products. First I loop through the number of items which need to be shipped alone, then I loop through the shipping rates. What I want is each group to be able to have 1 selection and pass along the params for use in the controller.

I need the ability to iterate or count the ss_ship_info so that each name/value will be different params. I have tried both 'ss_ship_info[@counter]' and 'ss_ship_info'[@counter] (this one has really unexpected results, if I have 3 items. The first two act like a single group but the third seems to be an individual group.)

Does anyone know a solution for my problem or at the very least could point me in the direction of a guide relating to the subject?

##CODE##################

<% @sscount.times do %> #First Loop

   <% for rate in @ups_ss_rates[@counter] %> # Second Loop       <label>          <%= radio_button_tag('ss_ship_info'[@counter], rate[0]) %>          <%= rate[0] %> - <span class="money"><b><%= sub_number_to_currency((rate[1])) %></b></span>       </label>     <% end %>

   <% @counter += 1 %>

<% end %>

The formtastic gem might be able to help you. https://github.com/justinfrench/formtastic

It makes writing forms a lot easier and has helpers for writing groups of buttons and stuff. Here's an example from the readme on github... f.input :authors, :as => :check_boxes, :collection => User.find(:all, :order => "last_name ASC")   f.input :authors, :as => :check_boxes, :collection => current_user.company.users.active   f.input :authors, :as => :check_boxes, :collection => [@justin, @kate]   f.input :authors, :as => :check_boxes, :collection => ["Justin", "Kate", "Amelia", "Gus", "Meg"]   f.input :author, :as => :select, :collection => Author.find(:all)   f.input :author, :as => :select, :collection => { @justin.name => @justin.id, @kate.name => @kate.id }   f.input :author, :as => :select, :collection => ["Justin", "Kate", "Amelia", "Gus", "Meg"]   f.input :author, :as => :radio, :collection => User.find(:all)   f.input :author, :as => :radio, :collection => [@justin, @kate]   f.input :author, :as => :radio, :collection => { @justin.name => @justin.id, @kate.name => @kate.id }   f.input :author, :as => :radio, :collection => ["Justin", "Kate", "Amelia", "Gus", "Meg"]   f.input :admin, :as => :radio, :collection => ["Yes!", "No"]
