I am using greesock and superscrollorama and I am having a problem with animating some sections of my site.  


  1. Uncaught TypeError: Cannot read property 'top' of undefined jquery.superscrollorama.js:99
    1. s.dispatchEventTweenMax.min.js:16
    2. f


Everything works perfectly on my localhost but I keep getting the same error when on a live site. you can see it here http://efc.demosite.me.uk/


Any help would be much appreciated thanks :)

What is exactly the problem?, something that should is not animating?.


Knowing exactly what's not working would help to pin point the issue; note that if you're getting an error with TweenMax.min.js use the production version of the code, but I'm only getting the superscrollorama issue on line 99 when I open the site.


But mainly the error has to do with some problem with a particular DOM element that is not defined, try creating variables for the elements your animating via scrollorama and pass those instead and see what happens. Also you're adding two different versions of JQuery (1.8.3 and 1.9.1).


For your navbar you could give the scrollTo plugin a try.


Hope this helps,
