I do appreciate your taking the time to provide input and recommendations.
I have tried every option I can thing of to deal with this issue. The sketch fails if you try to define them in the constructor without the “new” statement. Using the “new” declaration - and if you run the sketch, they appear to be properly defined in the constructor - but not recognized as being defined in the method.
The problems seem to associated with the method recognizing the array that is defined in the constructor, but it does recognize the int “nCell”.
I have tried to “this.” these class variables and that doesn’t help. I want object in the class to have different values of the 2D array variables as defined when each constructor in invoked … if that makes sense to you.
Thanks again, I will keep trying!
