What is happening right now?

One last question, Will the scores be updated in real-time? So if User 1 updates a score while User 2 is in the application, will User 2 be able to read that score? Or will they have to refresh the page before the information comes through?

What I do for situations such as this is instead of "removeObject.(this)" make it "removeMe = true" Then at the LAST line of act(), put a method called "checkRemove()" which is just <Code Omitted> Its a bit more complicated but makes things easier the more methods you have.

I have the book here, and the sample looks fine to me. What are the errors you are getting, exactly? With that info, we can help to track down the problem, but here's a couple of thoughts:

• The book chapter is similar to the online tutorials, but the online tutorials use a slightly different scenario. If you're using the book, make sure you started with the little-crab scenario that comes with the book, not the one that's online
• The code shown in 3.2 still needs the class declaration around it. That is, the code in 3.2 replaces the middle of 3.1 (the public void act bit), but you still need the outermost parts from 3.1
