Hopefully easy, passed object to constructor, need for event

Question

Ok, the current scope of my program is currently two frames, in two files, Login.java and Select.java (if you have not been following my neverending question saga)
I create an instance of Select from within the Login file, and i pass to the constructor of select, the Login object created, so Select can have access to what was entered in the text field of Login via a getName function, that works.
Now i want to have the "Back" button in Select close the select frame, and re-open the Login frame ie setVisible(false) and setVisible(true) respectivly...
Now once before, i noticed if i tried to make the visibility false of Login, from within the file that i created that Login object, i would get odd errors. So i figure if i want Select to close itself, i would pass it the object that Login created of Select.
But, the event code for the button has no idea what i passed to the constructor of Select (the event code for the button IN select)
So how would i go about letting my lil button know what i passed to the constructor of the class that it is in?
I assume this is an easy question, at least i hope so
Here is some relevent code:
// from Login.java, within the event for pressing "next" after validating the name within the text field.
selectframe = new Select(loginframe, selectframe);
selectframe.setSize(500, 350);
selectframe.setTitle("Select the midget");
selectframe.setVisible(true);
// Select.java
public Select(Login passed, Select selectpass)
          passed.setVisible(false);  //works fine...
          // GUI code
public void actionPerformed(ActionEvent f)
      if (f.getSource() == jbtBack)
           System.out.println("Back pressed");
           selectpass.setVisible(false);  //Error: selectpass is undefined
           passed.setVisible(true);  //Error. passed is undefined

import java.awt.*;
import java.awt.event.*;
public class ClassA extends Frame implements ActionListener
     public ClassA() {
          setTitle("ClassA");
          addWindowListener(new WindowAdapter()     {
               public void windowClosing(WindowEvent e) {
                    System.exit(0);
          clb = new ClassB(this);
          createFrame();
     private void createFrame() {
          setSize(300, 200);
          Button b = new Button("OK");
          b.addActionListener(this);
          add(b);
          show();
     public void actionPerformed(ActionEvent ae) {
          clb.frame2();
     public static void main(String args[]) {
          new ClassA();
     private ClassB clb;
class ClassB extends Frame implements ActionListener
     ClassA cla;
     public ClassB(ClassA passed) {
          cla = passed;
     void frame2() {
          setTitle("ClassB");
          setSize(300, 200);
          setLocation(300, 200);
          cla.setVisible(false);
          Button b = new Button("OK");
          b.addActionListener(this);
          add(b);
          show();
     public void actionPerformed(ActionEvent ae) {
          setVisible(false);
          cla.setVisible(true);
          return;
}These two classes each display a single button. When one is clicked, its frame becomes invisible and the other frame appears.
