Class calling the int: http://gyazo.com/bb8d8532a9a93491f97122cba4a8c331

It claims the int does not exist...

Answer 1

You are declaring it in a local context, so it is only visible within the main method. Try setting it as a class property.

Answer 2

Your variable a was declared in the Main method (so it is local to that method). You might get that variable value to the "called class" several different ways (not sure which may apply, provide full code):

• Declare variable in "main" class; provide method in "main" class to call and get the variable
• Find a way to pass the variable to the UI classes and then call your method with that variable value.
