Hi, I am very new to Mathematica and am helping a friend with his invention. The notebook below was created with Mathematica 12 Home Edition on Windows 10. I am trying to share it with my friend by sending him the cdf and asking him to load it in the Player. Unfortunately the Manipulate function at the end only displays an empty plot with an x and y axis when I open it in the Player myself. What am I doing wrong?
Thank you, Christoph Wagner
