I am in my first java class and I am writing an amortization program. I have gotten every thing to work correctly thus far except when I try to put in an outer loop I get the following error:

1 error found:
\gnixon00Lab3Test.java:116: cannot find symbol
symbol : variable restart
location: class gnixon00Lab3Test

Here is my code could you please tell me what it is that I am doing wrong?
