The other suggestions you have received are good places to start.  I'd add only one other - that you consider running the code inside an IDE and single-stepping through as you watch what happens to the variables.  As you get a better and better feel for what the code is doing, you can move up from single stepping to setting break points before and after places you are still scratching you head over.
