Just to clarify what Dan's saying: variables generally only
live for the
life of the request they were created within (with the
exception of
session-, application- and server-scoped variables). So a
variable set
during the preceding request ("the referring page") will not
exist on the
subsequent "page". Hence isDefined() returning false.
