I am trying to set more than one id in the add action.

cart_controller.rb

class CartController < ApplicationController
  before_filter :login_required
  before_filter :find_cart
  
  def add
    @cart.save if @cart.new_record?
    session[:cart_id] = @cart.id
    recipe = Recipe.find(params[:id])
    LineItem.create! :order => @cart, :recipe => recipe, :price => recipe.price
    @cart.recalculate_price!
    flash[:notice] = "Recipe added to cart"
    redirect_to '/cart'
  end
  
  def remove
    item = @cart.line_items.find(params[:id])
    item.destroy
    @cart.recalculate_price!
    flash[:notice] = 'Item removed from cart'
    redirect_to '/cart'
  end
  
  def checkout
    @cart.checkout!
  end
  
  private
  def find_cart
    @cart = session[:cart_id] ? Order.find(session[:cart_id]) : current_user.orders.build
  end
end

index.html.erb

<!-- Recipes to be submitted -->
<%= form_tag "/cart/add/:id", :method => :get	  do %>
	<table cellpadding="0" cellspacing="0" border="0" class="display">
		<thead>
			<tr>
				<th><input type="checkbox" class="headSelect"/></th>
				<th>Recipe #</th>
				<th>Description</th>
			</tr>
		</thead>
		<tbody>
			<% @recipes.each do |recipe| %>
			<tr >
				<td><%= check_box_tag recipe.name, recipe.id %></td>
				<td>RCP-<%= recipe.id %></td>
				<td><%= link_to recipe.name, recipe_path(recipe) %></td>
			</tr>
			<% end %>
		</tbody>
	</table>
	<%= submit_tag "Submit for processing", :disable_with => "Please wait..." %>
<% end %>

I am thinking my :url and :controller => :cart, :action => :add are not working very well. Am probably not processing the array.

Have an extra eye, HEEEEEEEEEEELP
