Powershell not reading .txt lines - powershell

Question

I cannot get PowerShell to run this .txt file, what am I doing wrong? I tried changing the name of the .txt and checked passed scripts and everything seems to be the same but I keep getting an error saying that the ".txt in invalid"
$POSName = "$PSScriptRoot\Bex.txt"
foreach ($POS in (Get-Content $POSName)) {
$Bex = Get-Service -ComputerName $POSName | Where-Object { $_.name -eq "BexServ" }
}
If ($Bex -eq $null) {
# Service does not exist
Write-Host " doesn't exist." -ForegroundColor Red
}
Else {
# Service does exist
Write-Host "The $($Bex.Name) service found." -ForegroundColor Green
If ($Bex.Status -eq "Running") {
# Stop Service
Set-Service -status stopped -ComputerName $POSName -name $Box.Name -ErrorAction Stop
Write-Host "The $($Bex.Name) successfully stopped." -ForegroundColor Green
}
else {
#service already stopped
If ($Bex.Status -eq "Stopped") {
Write-Host "The $($Bex.Name) service already Stopped." -ForegroundColor Green
}
}
}

As commented, you are using the wrong variable in the loop. The code is reading the text file just fine, it is Get-Service that cannot deal with a path to a file in the -ComputerName parameter.
Also, the placing of the if..else should be inside the loop, not after.
Try
$POSName = "$PSScriptRoot\Bex.txt"
foreach ($POS in (Get-Content $POSName)) {
$Bex = Get-Service -ComputerName $POS | Where-Object { $_.name -eq "BexServ" }
If (!$Bex) {
# Service does not exist
Write-Host " doesn't exist." -ForegroundColor Red
}
Else {
# Service does exist
Write-Host "The $($Bex.Name) service found." -ForegroundColor Green
If ($Bex.Status -eq "Running") {
# Stop Service
Set-Service -status stopped -ComputerName $POSName -name $Box.Name -ErrorAction Stop
Write-Host "The $($Bex.Name) successfully stopped." -ForegroundColor Green
}
else {
#service already stopped
If ($Bex.Status -eq "Stopped") {
Write-Host "The $($Bex.Name) service already Stopped." -ForegroundColor Green
}
}
}
}
It might also be a good idea to output the computername ($POS) in the Write-Host lines too
