was another variable?

Hi everyone,
I'm trying to do the following:
I have a variable containing list of my printers:

$printers="Printer1,Printer2,Printer3"

And I have lists of users who should have access to those printers. These lists of users are kept in variables as well:

$Printer1="user1,user2,user3"
$Printer2="user5,user4,user2"
$Printer3="user4,user1,user10"


And I want to add printers to users in following manner:

$ind=$Printers
While InStr($ind,',') <>0
$delta=InStr($ind,',')
$prin=Substr($ind,1,$delta-1)
$ind=Right($ind,Len($ind)-$delta)

If Instr($prin,@USERID)>0
$prn_name=Left($prin,InStr($prin,',')-1)
AddPrinterConnection ("\\server\"+$prn_name)
Else
? 'No printers for this pal!'
EndIf
Loop

The problem I have is that when I get the printers name (say printer1) and store it as $prin variable, I get $prin value = printer1. But I want it to be "user1,user2,user3"
in other words, I want to refer $prin variable which points to $printer1 variable and get the value of $printer1.

Thanks!
