Hi,

I am getting this error and just can not figure out what is causing it. I have looked at code from 2 different books. I have google searched.

Here is part of my program that contains the code giving me problems. I posted the program from the beginning to the problem code in case there is something up above it that I don't have coded right yielding the error.

import java.awt.EventQueue;

import javax.swing.JFrame;
import java.awt.Label;
import java.awt.BorderLayout;
import java.awt.Button;
import java.awt.TextArea;
import java.awt.Choice;
import javax.swing.JRadioButton;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JButton;
import javax.swing.JLabel;
