Ruby on Rails

Environment: Rails 3.2.3

This is my first attempt at doing a dropdown menu in a Rails
application. I tried looking for help on the topic, but what complicated
things is that the term dropdown menu is used for actual dropdown menu
(page menu), as well as what is dropdown lists, form options, form
selections, etc.

I found a pointer to https://github.com/dkeskar/rails-jquery-dropdown,
and following the instructions, I downloaded jquery_dropdown_helper.rb:
) and placed it in /lib

In my Gemfile, I have the following:

gem 'jquery-rails'

I downloaded jquery_dropdown_helper.rb:
https://github.com/dkeskar/rails-jquery-dropdown) and placed it in /lib

In _header.html.erb, I have the following:

<% require 'jquery_dropdown_helper' %>
....
<%= hidden_field_tag :sort_criteria %>
<%= dropdown_tags :sort_criteria, 'Select Criteria',
   %w(Category Status Amount-High Amount-Low) %>

Here's the error code I'm getting:

undefined method `gsub' for :sort_criteria:Symbol

Any ideas?

Attached is the jquery_dropdown_helper.rb
