but when include website, every thing working ok

why getting error??

what happens if replace js src with

http://cdn.jquerytools.org/1.2.5/full/jquery.tools.min.js

or change jquery to:

$(function() {      // initialize scrollable     $(".articles").scrollable({ vertical: true, mousewheel: true });  });
