	hi,

	you can do this a couple of ways.

	1.  create a property, one of the tabs, which can apply to the
whole site (from the very top folder down) or from within a directory to
apply only to the contents within that directory/folder.

	2.  if you are going to use a set of variables which are all
related, you can create a dtml document, let's say 'global', then define
the various variables you will use via the <dtml-call "REQUEST.set('',)">
method.  in documents where you want to use these variables, the first
line in each document can be a dtml-var call, e.g., <dtml-var
global>.  whatever variables you have defined in 'global' will then pass
to the document, and you can call them, reassign them, or whatever.

	hth.

	ciao!
	greg.
