Brian,

Thanks for your help!

Yeah, that's what I'm doing also - pull out the most nested one first, then
work out from there.

I want to count from 1 to 9 in steps of three - So we start with $page being
whatever it is now, and add to it as $chapter escalates. For the purposes of
demonstration, this will produce chapter 1, page 1-3, chapter 2 page 4-6,
chapter 3, page 7-9.

You can't just pull that step out - it doesn't work, so you have to explicitly
say that $page = itself.

This behavior has been verified with echo statements.

Aren't these functionally the same? (true/false wouldn't make any difference
here because you are only parsing one example of the handle anyway, right?)

I'll be testing your sample code at the bottom to see if it fixes the problem
(hopefully) today - I have a MASSIVE number of axes in the fire right now!

The urgency on this has diminished a bit since I cheated and hard-coded some
HTML into the PHP code for the alpha release of the software, so I have a
*little* bit of time to figure this out before I have to "go live" with
anything.

Thanks SOOOO MUCH for your feedback!

allows stuff like this to be cataloged, sorted, and made easy to find! - one of
the most exciting projects I've ever had anything to do with)
