Mr. Man,

Glad you're enjoying the book!

I suspect a typo in your program, most likely something with indenting. Please carefully check the indenting, and try it again. If that doesn't work, send your code in an e-mail attachment to, and we'll have a look.

(Unfortunately, this forum doesn't work for posting code, as it strips off the indentation. We will soon be moving the forum to a new site with better functionality.)
