Use PTVs.  The name of the variable is something consistent across all pages
so you can scan for it.  If it doesn't exist then you have some appropriate
default chosen.

Er...  Where are you finding the ReadVar function?  Do you mean PageVar()?
Why not just use the function as it stands?  You can do a quick CondAuth()
ahead of time if you need to check authorizations...

If you do need to understand the internals of PageVar or PageTextVar try
putting in some of those echo statements I recommended earlier, figure out
the majority of it, and if you have specific questions go ahead and post
