Treehouse TeacherI tried to look at this code in Eclipse but there's too much that I don't understand. There is a lot going on, so it's easy to get lost without consistent indenting and brackets.
Let's try this: copy and paste your code into a "code beautifier": http://prettyprinter.de/index.php
Then take the output from there and paste it back into Eclipse. That will at least help get things indented consistently, which may help you track down the error.
