Thanks to Lonks new spiffy color code... it found the error for me...

You are missing the closing quotes around the messages about setting the printer in both of these sections...

 Code:
IF INGROUP("Admin")
	$=AddPrinterConnection ("\\Server1\Principal B_W")
	$=AddPrinterConnection ("\\Server1\Principal Colour")
	$=AddPrinterConnection ("\\Server1\Reception Office B_W")
	$=AddPrinterConnection ("\\Server1\Resource Rm B_W")
	$=AddPrinterConnection ("\\Server1\Principal Rm Colour")
        ? "Added printer connection....
ENDIF

IF INGROUP("Students")
	$=AddPrinterConnection ("\\Server1\Resource Rm B_W")
        $=SetDefaultPrinter ("\\server1\Resource Rm B_W")
        ? "Added printer connection....Setting default to Resource Rm B_W"
	$=AddPrinterConnection ("\\Server1\Middle Syn B_W")
	$=AddPrinterConnection ("\\Server1\Room12 B_W")        
        ? "Added printer connection....
ENDIF
