Hi. I was trying to reverse engineer this demo using the Modifiers plugin:  See the Pen QEdpLe by GreenSock (@GreenSock) on CodePen   I got it to go downwards on the Y access okay, but I'm running into issues getting to get it to go up. Any help? Also, if you could explain how the % mod works, that would be great. Please no jquery. See the Pen MWoMXgr by pixelbakery (@pixelbakery) on CodePen
