You replied to a different unrelated topic. I put your post in a new topic. I also put code tags around your code so that it's easier to read.
Now, I'm not sure what error you're getting, you might want to copy an paste the exact error message, but I can tell that the structure of your code is wrong. Your braces don't match up nicely, and it appears you have a start() method inside your main() method. I don't think this is as intended.
