JRadioButton's not being clicked when clicked--?

I have a JMenu with some radio buttons...For some reason, when I click the stupid things, they won't do anything...and by that, I mean they want change their state to being clicked(as in the circle being filled)..It's like they are disabled...I'll post the snippets of code with them in it:

Code:

---

        JMenu formatMenu = new JMenu("Format");
                ButtonGroup bg = new ButtonGroup();       
                rb0 = new JRadioButton("###",false);
                rb0.addActionListener(this);
                rb2 = new JRadioButton("###.##",true);       
                rb2.addActionListener(this);
                rb4 = new JRadioButton("###.####",false);
                rb4.addActionListener(this);       
                rb6 = new JRadioButton("###.######",false);
                rb6.addActionListener(this);
               
                bg.add(rb0);
                bg.add(rb2);
                bg.add(rb4);
                bg.add(rb6);
                formatMenu.add(rb0);
                formatMenu.add(rb2);
                formatMenu.add(rb4);
                formatMenu.add(rb6);

Why would I not be able to click these buttons?

I can post the whole thing if you would like ?

Try adding a JRadioButtonMenuItem to the JMenu instead of adding a JRadioButton

Wow! That worked; I never knew such a thing existed...Thank you.
