Capybara find error

Simple one I ran into when using Capybara.find(css_selector)

The following code

find(".manifest_section[data-title='#{parent_section_name}'] .new_section ")

Throws this error

Nokogiri::CSS::SyntaxError Exception: unexpected '$' after 'DESCENDANT_SELECTOR'

Remove the whitespace at the end yo :P
