need fix for responsive drag&drop function

1. Look at this site: [login to view URL] It works exactly as I want it to (responsiveness): On big screens, the sentence is displayed horizontally, on small screens in a vertical layout. 2. Now I copied the entire code used (javascript & CSS) into a larger project, expecting it to behave just like that. But it doesn't work. Check out [login to view URL], just enter a dummy name and a dummy email-Adress for it to work. Answer the first two questions any way you like and you will find the sentence reconstruction exercise, which doesn`t work. I need the functions dragInit() or setdrag() fixed so the drag&drop works responsively on big and small screens. NONE of the other JavaScript must be edited! CSS can be edited according to your needs. The template I used is a bit tricky, please contact me if you have any questions.
