DriveMapAdd with 2 variables

[JLC123]

I'm trying to convert my old, clunky utilities to .au3 files. Many of these first require mapping into a remote PC. Remote PCs are grouped by numbers which share an base IP and then seperated by letters varying only the last octet of the base IP. I use an IPLIST.INI file which I don't believe I have to alter for this task.

I've tried both NET USE and DriveMapAdd and neither are working for me. I think the problem is in the way I've tried to get and use the 2 necessary variables.

INI FILE:

12=XX.XXX.XXX

13=YY.YYY.YYY

14=ZZ.ZZZ.ZZ

CODE:

Dim $A = "1.\c$"

Dim $B = ".2\c$"

$mac = InputBox("Tools","Please select PC number")

$list= IniRead("C:\data\wan\iplist.ini", "list", "$mac", "NotFound")

DriveMapAdd( "M:", "\\"$list, $B"")

OR - RunWait("net use M: \\"$list, $B"")

either way returns an error in expression, so I removed the variables one at a time to see which one was causing me the problem, but they work alone, just not together. I'm out of troubleshooting ideas.
