Answer 1

One of your problems is that you are creating a new Page3_NewUser object in the p3_Continue ActionListener and expecting it to contain all of the data contained in the current Page3_NewUser object. Well it won't as the two objects will be totally distinct. You need to use the current Page3_NewUser object in the ActionListener. One way to do this is to use Page3_NewUser.this object like so:
            Saving s = new Saving();
            s.Save(Page3_NewUser.this);
