simplesolution

I found the problem. As your advice, I removed all code and made simple. and then, I checked one by one. If I removed below code, Everything is ok. // curve moving bezier jQuery(document).ready(function(){ TweenMax.to(document.getElementById("box1"), 6, { type:"soft", bezier:[ {left:100, top:250}, {left:600, top:0}, {left:300, top:100} ], ease:Power1.easeInOut, repeat: -1, yoyo: true }); }); This code is fine in home. It works well. but In the other page, If I removed html markup(for above code), It made some error. https://codepen.io/mogwai90/pen/xxKJawJ

I'm testing green sock in WordPress. ( beginner) error : Uncaught Cannot tween a null target ----------------------------------------------------------------- // curve moving bezier TweenMax.to(document.getElementById("box1"), 6, { type:"soft", bezier:[ {left:100, top:250}, {left:600, top:0}, {left:300, top:100} ], ease:Power1.easeInOut, repeat: -1, yoyo: true }); --------------------------------------------------------------------- -> this code makes above error. I didn't find the solution yet.
