Please Help - I'm Stuck on Ruby - Build a ToDo List - Editing Todo Lists

I have Error Testing Issues encountered at 5:43 of ODOT-Stage1-video7 that are different than Jason's error and I can't get past the error - I have double checked my code in file index.html.erb

<tr id="<%= dom_id(todo_list) %>">

I have doubled checked my code in edit_spec.rb These code markups are all over the place... sorry about that!

require 'spec_helper'

describe "Editing todo lists" do
    it "updates a todo list successfully with correct information" do
        todo_list = TodoList.create(title: "Groceries", description: "Grocery list.")

        visit "/todo_lists"
        within "#todo_list_#(todo_list.id)" do
            click_link "Edit"
        end

        fill_in "Title", with: "New title"
        fill_in "Description", with: "New description"
        click_button "Update Todo list"

        expect(page).to have_content("Todo list was successfully updated")
        expect(todo_list.title).to eq("New title")
        expect(todo_list.description).to eq("New description")
    end
end

Jason's error at this point on the video was on his example line 17...

        expect(todo_list.title).to eq("New title")

But my error is on line 8 (of the example above)

        within "#todo_list_#(todo_list.id)" do

The Failures code in the git console is as follows:

1) Editing todo lists updates a todo list successfully with correct information
    Failure/Error: within "#todo_list_#(todo_list.id)" do
    Nokogiri::CSS::SyntaxError:
     unexpected '#' after '[#<Nokogiri::CSS::Node:0x48a21e0 @type=:CONDITIONAL SELECTOR, @value=[#<Nokogiri::CSS::Node:0x48a2258 @type=:ELEMENT_NAME, @value=["*"]>, #<Nokogiri::CSS::Node:0x48a2a50@type:ID, @value=["todo_list_"]>]>]'
        # ./spec/features/todo_lists/edit_spec.rg:8:in 'block (2 levels) in <top (required)>'

Now, I can only assume that this has something to do with CSS id attribute in table row within the index.html.erb

<tr id="<%= dom_id(todo_list) %>">  

Now I am at a loss how to get past this error....

PS, I am NOT using the virtual machine environment on Windows. I'm using Ruby 2.0.0p481 (2014-05-08) [i386-mingw32] on Windows 7 and rails '4.1.4'

Everything has been working fine up to this point.... I'm Stuck ;(

Thanks to anyone who even PEEKS at this!
