I do not understand what is wrong

Unity Engine
1

As I refer the int if you do not let me put “,” and there are":"

2

How is the variable declared? Is it a variable in the Save method (intellisense is blocking is) or a class variable?

3

is a public static void only the scipt isnt static

4 
    public class MyClass {

        int myInteger = 0;
        public static void Save()
        {
            // myInteger (reference type) cannot be used
            // within a static method because the class is not instantiated
        }
    }
