Everything else is working properly, the directions were to add a TitledBorder with the value "Customer Order" to the panel instance. I am doing what the book says only the border is not showing up. There are 6 panels on this content pane, how do i get the border to go around all of it?

Can someone give me a visual, I learn more visually.

Two things:

first: your Panel (to which you add the Border) is never added to your frame so no wonder it's Border does not show up
second: a JComponent cannot be at two places at the same time so you add in your buildPanel() method messageLabel, textField, ... to your panel... but later on you add them to panel1, panel2, panel3, ....
by doing that, you remove them from where they were (panel) and put them into the other panel

you see them because you add panel1, panel2, panel3.... to your frame
but the panel with a Border is never added and would contain nothing

I am confused then, if I take away the add(panel1) etc. then nothing shows up but then the border shows up. I am not sure I am understanding how to fix this....

You should not only remove the add(panel1), ....
you should completly remove them (thei definition and the lines that add() something to them

[tricket_7]

I see, but when I remove that the items are not longer in the order they needed to be in.
I have the GridLayout manager this should be in two columns and 3 rows, the first row should show the messageLabel and text box in blue
2nd row should show the submit and clear button
3rd row should show Total Cost and REsults the text in Red.
So how do i get them back in the order they were to be in?

Just change the order you add them

GridLayout are fill row by row so the first add() will put the component in 0,0 the second in 0,1 the thirs in 1, 0.....

I made these changes to my code, but maybe I have the GridLayout wrong, the order is correct for the add(). but the panel displays everything in one row, I attached the updated version of my code.
I really appreciate your help.

It is the JPanel() that should have the GridLayout not the frame into which you put the JPanel

//Add a GridLayout manager to the content pane.
// setLayout(new GridLayout(3, 2));

...

panel = new JPanel(new GridLayout(3,2));
