Yes but what is that? It was this:
Instead of declaring new arrays in Form_Load, you should work with the ones you've declared at class level.

You might think I'm a bit rude not to give you the correct pieces of code to solve your problem, but I'm actually trying to help you understand the problem yourself, so you can fix it yourself.

Right now you've removed the local arrays you declare at Form_Load, thats good, you dont need them.
However the arrays you've declared at class level are not instantiated, they havent been created. You obviously already know how to create new arrays as you did so in Form_Load previously.
