ars technica recipe

[tom_a_sparks]

I am trying to add these feeds to the ars technica recipe

             (u'Ars Features (All our long-form feature articles)'        , u'http://feeds.arstechnica.com/arstechnica/features')
             (u'Technology Lab (Information Technology)'        , u'http://feeds.arstechnica.com/arstechnica/technology-lab/')
             (u'Ministry of Innovation (Business of Technology)'        , u'http://feeds.arstechnica.com/arstechnica/business')
             (u'Staff Blogs (From the Minds of Ars)'        , u'http://feeds.arstechnica.com/arstechnica/staff-blogs')

but I keep getting this error message when I go to save
