Could anybody help me out?

import java.awt.GridLayout;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class WizardGUI extends JFrame implements ActionListener {
    private JLabel enterName;
    private JTextField name;
    private JButton prev, fow;
    private String storeName = "";

WizardGUI(){
    super("Wizard");
  name();

}

void name()
{
      JPanel FPanel = new JPanel();
 this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
  this.setLayout(new FlowLayout());
  // JLabel textLabel = new JLabel("lol");
 //textLabel.setPreferredSize(new Dimension(300, 100));
 // frame.getContentPane().add(textLabel); 
  //prev = new JButton("<--");
  fow = new JButton ("-->");

 this.add(FPanel);  
  enterName = new JLabel("Enter Your Name: ");
  name = new JTextField(10);
  enterName.setBounds(60, 30,120,30);
  name.setBounds(80,60,130,30);
  this.setSize(300,390); //set frame size
this.setVisible(true);
 FPanel.add(enterName);
 FPanel.add(name);
  //FPanel.add(prev);
   FPanel.add(fow);
   fow.addActionListener(this);

}


 void enter()
       {
JPanel panel2 = new JPanel();
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
  this.setLayout(new FlowLayout());

//prev = new JButton("<--");
  fow = new JButton ("-->");

 this.add(panel2);  
  enterName = new JLabel("Enter Your Name: ");
  name = new JTextField(10);
  enterName.setBounds(60, 30,120,30);
  name.setBounds(80,60,130,30);
  this.setSize(300,390); //set frame size
this.setVisible(true);
 panel2.add(enterName);
 panel2.add(name);
  //FPanel.add(prev);
   panel2.add(fow);
   fow.addActionListener(this);  
this.getContentPane().removeAll();
validate();
repaint();
this.add(panel2);
       }

void add()
{

}

void select()
{

}
 @Override
    public void actionPerformed(ActionEvent e) {
       if  (e.getSource() == fow) {
storeName = name.getText();
enter();

//JOptionPane.showMessageDialog(null, "hello " + storeName);
}


       }
    }

Thanks :)

You both extend JFrame and you create your own JFrame. This means you have two instances of JFrame. One is your WizardGUI class which I'm guessing is referenced in your main somewhere and the other is a local variable named frame.

In the constructor you are building everything in the frame instance. In the Sscreen method you are modifying the this instance so nothing that you've done to the frame instance is modified.

You should get rid of the local variable frame and replace all references to it with this.

Also, you should call super("Wizard") as your first line in the WizardGUI constructor. Calling parent constructors is important and everyone forgets to do that.
