You have a
NullPointerException, from what I understand he’s in classMatrizon line 21.– Math
@Math after fixing the first error first arises this error that I put in question if you can take a look worth.

Apparently it’s the same error in the same class, but it’s switched to line 26. Maybe it’s the case that you add your code to your question to try to identify the root cause of the problem.
