Hello and thank you Mike Besso and Rohit Namjoshi.
Thank you a lot for all this time.
I am new with Mathematica.
You told me : "What exactly do you mean by "It doesn't work"?". I can't see the movie. This is a screen print : https://www.cjoint.com/c/JGidex3cCXH .
It is written "running". Can you help me please ?
Thank you.
