try doing : isDefined("session.isLoggedIn")
NOT
isDefined(session.isLoggedIn)
example 2 is actually tryng to evaluate the variable as opposed to check for

I get the following error...
Error Occurred While Processing Request
Error Diagnostic InformationAn error occurred while evaluating the
expression: REQUEST.isLoggedIn = IsDefined(SESSION.isLoggedIn)Error near
line 23, column 11. Error resolving parameter SESSION.ISLOGGEDIN The
session variable ISLOGGEDIN does not exist. The cause of this error is very
likely one of the following things: The name of the session variable has
been misspelled. The session variable has not yet been created. The session
variable has timed out.The error occurred while processing an element with
a general identifier of (CFSET), occupying document position (23:5) to
(23:62).Date/Time: 03/20/02 11:06:35
