Please help...my browser can't display applets

Question

I know it might sound inept to be asking something about my mozilla browser in this forum but right now I am studying Java and using my browser to view the applet exercises I make. I am particularly in the methods section where you have to make recursions (I am using JAVA 2 how to program Third Edition by Deitel). I made my own version of the fibonacci program in the book . It has a GUI, action listener and the method where all the calculations take place. Unfortunately, when I test it on my brower, Mozilla Fireforx, it just displays the GUI and whole program does not work. The compiler, in this case javac, cannot sense anything wrong and I take it that my code is correct. However nothing still happens when I test it on my browser. As previously mentioned, it just displays the GUI and that's all. I really do not know what is wrong. Is it with my code or with the browser? Or is with the fact that I am using an outdated version of JAVA 2 how to program with a new version of J2SDK that makes my code incompatible with the new technology? please help. TY
Here's my code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class AppletCode extends JApplet implements ActionListener {
     JLabel inputLabel, outputLabel;
     JTextField input, output;
     public void init(){
          Container c = getContentPane();
          c.setLayout(new FlowLayout());
          JLabel inputLabel = new JLabel();
          inputLabel.setText("Enter an Integer and press Enter");
          c.add(inputLabel);
          JTextField input = new JTextField(10);
          input.addActionListener(this);
          c.add(input);
          JLabel outputLabel = new JLabel();
          outputLabel.setText("Fibonacci Value is");
          c.add(outputLabel);
          JTextField output = new JTextField(20);
          output.setEditable(false);
          c.add(output);
     } // GUI
     public void actionPerformed(ActionEvent e) {
          long number, fibonacciValue;
          number = Long.parseLong(input.getText());
          fibonacciValue = fibonacci(number);
          output.setText(Long.toString(fibonacciValue));
     } // Action Listener
     public long fibonacci(long x) {
          if (x==0 || x==1)
               return x;
          else
               return fibonacci(x-1) + fibonacci(x-2);
     } // Fibonacci Module
}

I don't see anything obviously wrong with your code, but it's been a while since i coded applets, so there might still be something wrong. What exactly does not work? You see the 2 labels and the text fields? Can you enter any text into the text field? Have you looked into the Java Console wether it prints any exceptions? (and please use the [ code][ /code] tags to mark your code (without the spaces obviously))
