I need to have one worksheet in two different databases (i.e., "clients" )
that is the same in noth in other words whenever we update names and
addresses in the clinets tab of the first workbook it is updated in the
second and vice-a versa. Is there a way to do this simply?

Being able to updtae the information in one workbook and have it updtaed in
the other, only is no longer useful due to many users using both.
