I reworded it some, but it works for me on 2000 using KiXtart v4.02

code:
$cc = 0
$key = 0

if Ingroup("Administrators")
$cc = 1
? " You are in the Admin group.."
GET $x
endif

CLS
if Ingroup("Power Users")
$key = 1
endif

if $cc = 1 and $key = 1

At (9,12) "Please choose one of the following classes:
1 Computer Concepts
2 Beginning Keyboarding
Selection : "
Get $selection
select
case ($selection = 1)
? "You chose option 1"
;use v: "\\server\xxxx$"
case ($selection = 2)
? "You chose option 2"
;use v: "\\server\yyyy$"
case (1)
? "That is not a valid option"
endselect
sleep 2
endif
if $cc = 1 and $key = 0
? "No choice Drive xxxx will be mapped"
;use v: "\\server\xxxx$"
endif
if $key = 1 and $cc = 0
? "No choice Drive yyyy will be mapped"
;use v: "\\server\yyyy$"
endif
