Variables add to MSI installation help

Question

Hi,
I am new to PowerShell. I am working on an install script that will install an MSI but I need to add some variables to the argument because it needs to be install on multiple computer from different servers. Here is the script I have written:
$IP=((ipconfig | findstr [0-9].\.)[0]).Split()[-1]
$IP2 = (([ipaddress]$ip).GetAddressBytes()[0..2] -join ".") + ".201"
$Hname = [System.Net.Dns]::gethostByAddress("$IP2").hostname
$Hname = $Hname.Substring(0,13
msiexec /i \\$Hname\Applications\DNA\DNAClient4.0.msi /l*v "C:\DNA40ClientInstall.log" INSTALLDIR="Q:\" DBNAME="PROD" EXEPATH="Q:\OSI\BANK\Exe" MAPPATH="\\$Hname\PROD"
DELETE64BIT="True" /quiet
Start-sleep -s 100

I know it is a little clunky but it works like a champ. The MSI install portion is where I need help because depending on the computer subnet it needs to install from that server on that subnet. $Hname is the variable for serve
name. The way it is written does not seem to work. Would like some direction on how to make this work.
msiexec /i \\$Hname\Applications\DNA\DNAClient4.0.msi /l*v "C:\DNA40ClientInstall.log" INSTALLDIR="Q:\"
DBNAME="PROD" EXEPATH="Q:\OSI\BANK\Exe" MAPPATH="\\$Hname\PROD" DELETE64BIT="True" /quiet
