It just isnt working correctly

Please explain what is not working correctly.

The only part working is the text field and the exit button.

That's good that some of it works. Now pick one part that does not work and explain all about what happens or does not happen.

Post moved from Applet section. Nothing to do with java applets.

The top two panels are blank, I can't see my radio buttons or check boxes.

Where do you add those panels to the GUI so they can be shown?

Between lines 80-97.

What is the line number where you add the top panel to the GUI.

Number line 80

Are you using the line numbers from your post? Here are lines 79,80 and 81

Code:

---

public static void main(String[] arguments)
{
    Assignment8 aFrame = new Assignment8();

---

Line 80 is the {

Look at the code you posted and use the line number from there.

Hnt: You have NOT added the top panel to the GUI

I was stating the number 80 from a smart phone and I see that it was not the exact line 80 now that I am logged into a regular computer.
But I'll look into the "hint" you suggested.
