1. You can use session variables to keep track of what they checked on
previous pages. Or you can plop it into a db to keep track of it.
2. If you store it in the db then you can just have it update the fields
they went back to and updated. The same for session storage. Then you can
have a wizard interface with a back and next buttons.
3. %udat can do it and will do it. %udat is for storing session variables.
%udat is a little tricky to setup, but its not that tough. Read all the
docs on Apache::Session to see how to set it up. I happen to set it up by
using MySQL and a sessions table and then setup everything in my Apache
startup.pl script every time Apache boots up. There are also other ways to
do it. You can use the filesystem, etc.

Subject: checkboxes in embperl
I was displaying rows of selection using checkboxes.
The problem is when there are too many selections (e.g. >100) to display,
my embperl page slows down.
I am planning to cut the selections into 25 rows per page. Users of this
page will just have to click next/previous button.
My questions are:
1. How will i know if there were selections checked in other pages?
2. How will i know if a user goes back to a certain page and unchecked
the previously checked selection.
3. Can %udat do this? How?
