Sort test still failing with error CSS element can't be found. Any ideas?

    Given that there are events                 #
features/step_definitions/sortView.rb:2
      Unable to find css "span" with text "Event Name"
(Capybara::ElementNotFound)
      ./features/step_definitions/sortView.rb:3:in `/^that there are
events$/'
      features/sortView.feature:11:in `Given that there are events'
    When I click the "Event Name"               #
features/step_definitions/sortView.rb:30
    Then the events should be in alphabet order
SortView feature still broken. Firefox does not render when running cucumber features/sortView.feature
