Rediculous amounts of problems

Question

Alright so in the last 30min I've created a recipe for disaster and stressed myself out. Can't seem to get anything working properly anymore and these forums appear to be a last resort :(
I wanted the Summary button to display Grand Total the same way the textArea.append does, cost of each make total....number of cars of that make...ect.
Basically I wanted the output to be as such....
Cadillacs: 6
Cost: $2902.00
Fords: 2
Cost: $209.00
Toyotas: 5
Cost: $893.00
Total Number of Cars: 13
Grand Total Cost: (whatever 2902 + 209 + 893 is)
I kind of stopped half way because I'm going out of my mind trying to get anything to work right.
And getRootPane().setDefaultButton(calculateTotalButton); didn't work as easily as I thought it would, So I'm back to square one on that :(
Heres the code, help if you will, it's very much appreciated I promise. Otherwise I'm stuck in a rut and I'll have to find another way to go about this :(

}Thanks again for any help you push my way. Much Appreciated.
(Yes I'm aware this may be considered as 'Doing it for me', but I've tried for about 4 hours to get this moving
so this is why I'm asking for so much help.)

The formula is this:
Ask a specific question -- get lots of help.
Ask us to do this for you -- get lots of grief.
