1. create a session with all the checkbox uncheck values
2. us if, iif whatever to make the checkboxes recognise the values
3. make the next previous links form submissions and before writing the next
page write the checked boxes to the session
4. you will now be able to see what's been checked.
does that make any sense, I hope so.
oh and make sure you lock every thing that is writing to or reading from the
session, it's probably a good idea to duplicate the session to request so
that you need less locking.
