Hi,
I'm new and probably this is a dumb question.
I've got the error that you can see as subject. Actually, it seems a warning since the code provide a output that I like (many improvings are needed here), but I would like to give ride to these warning.

The answers provided in internet does not help me too much, so I asked to this forum.

The code that I have written is after my signature.
Thanks,
M
