Basic Action Listener not workin
[nobr]This may seem like a lot of code, "BUT" there's one simple line that's causing the error and its way at the bottom inside the actionlistener event.
For some reason the button called "cmdSubmit" isn't registering in the ActionListener event. Any ideas why?

import java.awt.*;
import java.awt.event.*;

public Survey()

cmbSleep.addItem("5-6 hours");
cmbSleep.addItem("6-7 hours");
cmbSleep.addItem("7-8 hours");
cmbSleep.addItem("> 9 hours");
cmbSleep.setEditable(false);// so user can't mess with the data
cmbSleep.setMaximumRowCount(3);
//adds the basic label + the comboBox
FlowLayout flowSleep =new FlowLayout(FlowLayout.LEFT,0,0);
