Restart a service on a remote computer

Question

So I am a little confused and would be gracious for some help here. In my PowerShell class I am tasked with the following:
Write a PowerShell script that can be used to restart a service on a remote computer. The script must do the following:
Accept a parameter to for the computer to restart the service on
Display a list of services running on that computer
Allow the user to enter the name of a service to restart
Display a message that the service on the specified computer is about to be stopped
Ask the user to hit the Enter key to continue
Stop the service on the remote computer
Display the state of the service on the remote computer after the stop command has been sent
Display a message that the service on the specified computer is about to be started
Ask the user to hit the Enter key to continue
Start the service on the remote computer
Display the state of the service on the remote computer after the start command has been sent
I'm a little confused about how to set the variables into the script. Here is what I have so far but I'm not exactly sure of the errors im getting within the ISE. Any help would be greatly appreciated. Thanks
$session = New-PSSession -ComputerName localhost
Enter-PSSession $session
Get-Service | sort-object -property `
@{Expression="Status";Descending=$true}, `
@{Expression="DisplayName";Descending=$false} | Where-Object {$_.status -eq "running"}
$userinput = read-host "Enter Service to restart:"
write-host "$userinput is about to Stop." -fore yellow -back magenta
Write-Host "Press any key to continue ..." $x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
Stop-Service -InputObject (Get-Service -ComputerName "localhost" -Name "$userinput"

Answer 1

Actually I will tell you the answer because you will not see it.
The issue is you are using ISE when you should be using CLI or don't use
$host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
This command is specific to CLI PowerShell.
¯\_(ツ)_/¯
