I am using TimelineMax.js and TweenMax.js to animate parts of a page which as they come into view everything is performing well but I keep getting this error in Console :


Uncaught TypeError: Cannot read property 'length' of undefined which refers to TimelineMax.js : 12


Could you help me about it please?


Thanks in advance.

Sorry I found what is causing this problem, I was using TweenMax V 1.11.2 with the latest version of TimelineMax so as soon as I replaced my TweenMax version with the latest one there error is gone, 


Thanks for such amazing libraries any way.

Glad you got it working. Just so you know: the TweenMax.js file includes all of TimelineMax, so using both files in your page isn't necessary.
