Currently, the only "working" figure-8 is design 2. Remix the project below and save it to your account. http://scratch.mit.edu/projects/14657389/ Rename it to LastName--Figure8s If you can't program all of the designs, make sure you change the Robot's opening to phrase to give the user instructions as to which numbers they can type in.
