Code below keeps returning -1 :-( HELP!

I have also used @wksta and "@wksta" as second parameter and they fail as well ...

? @wksta returns correct workkstation name

-------------------
;connect to Soc Grad Lab Printer if computer is on Soc Grad OU
IF INGROUP ("CASCOMP")
? @wksta
$rc = InContainer("OU=ou_Labs, OU=SocGradLab_OU, DC=cas, DC=univ, DC=albany, CD=edu", "PFARRELLOFF")

select
case $rc[0]=1
IF AddPrinterConnection ("\\p2\soc_gr_ric4510") = 0
? "Connecting to the Ricoh 4510 in the Sociology Grad Lab"
ENDIF
case $rc[0]=2 ? "RC is 2"
case $rc[0]=0 ? "RC is 0"
case $rc[0]=-1 ? "RC is -1"
case $rc[0]=-2 ? "RC is -2"
case 1 ? "RC is Unknown"
endselect
ENDIF
