Sorry, I don't and I suspect I'm not alone.
It's probably a fine book, but we don't all know it.

Good man Zed :-)

And here's the next problem.
This is a text based mailing list. As such the server often strips out
attachments as potential security risks. So we can't see the code (I'm
assuming you attached it?)

Without sight of the code its hard to know what's going on.
But I suspect some of these "functions" are actually variables
(or objects) and hopefully zed has already discussed those?

Can you repost but include your code inside the mail message.
Also try to post in plain text since HTML tends to get garbled
in transit.
