    I know that that's not the way to do it but I have to submit the GUI Applet after couple of hours and I just can't fix it myself. I've done everything else except adding a ComboBox with a "Male" & "Female". How can I just replace the CheckBox with an uneditable combo box and still make the "Send" button show the choice? That's my code:

        package MyApplet;
    
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    
    import javax.swing.ButtonGroup;
    import javax.swing.JApplet;
    import javax.swing.JLabel;
    import javax.swing.JOptionPane;
    import javax.swing.JTextField;
    import javax.swing.JRadioButton;
    import javax.swing.JCheckBox;
    import javax.swing.JButton;
    
    public class MyApplet extends JApplet {
        /**
         * 
         */
        private static final long serialVersionUID = 1L;
        protected JTextField mTxtName;
        //protected JTextField mTxtEmail;
    
        protected JRadioButton mRdbone;
        protected JRadioButton mRdbtwo;
        protected JRadioButton mRdbthree;
        protected JRadioButton mRdbfour;
        protected JRadioButton mRdbfive;
        protected ButtonGroup mRdbGroup;
    
        protected JCheckBox mChbSport;
        protected JCheckBox mChbTV;
        protected JCheckBox mChbMusic;
    
        protected JButton mBtnSend;
        protected JButton mBtnClear;
    
        /**
         * Create the applet.
         */
        public MyApplet() {
    
            mTxtName = new JTextField();
            //mTxtEmail = new JTextField();
    
            mRdbone = new JRadioButton("10-20");    
            mRdbtwo = new JRadioButton("21-30");
            mRdbthree = new JRadioButton("31-40");  
            mRdbfour = new JRadioButton("41-50");
            mRdbfive = new JRadioButton("51-"); 
    
            mRdbGroup = new ButtonGroup();
    
            mChbSport = new JCheckBox("Sport"); 
            mChbTV = new JCheckBox("TV");
            mChbMusic = new JCheckBox("Music");
    
            mBtnSend = new JButton("Send");
            mBtnClear = new JButton("Clear");
    
        }
    
        @Override
