Trying to add a role on a remote server using windows powershell.

Question

Im reading a book that wants us to install a role on a remote computer using powershell.  The comands below is what we are sopuse to use and nothing happens.  Does anyone know why?
function Invoke-WindowsFeatureBatchDeployment {
param (
[parameter( mandatory)]
[string[]] $ ComputerNames,
[parameter( mandatory)]
[string]
$ ConfigurationFilePath )
# Deploy the features on multiple computers simultaneously.
$ jobs = @()
foreach( $ ComputerName in $ ComputerNames) {
$ jobs + = Start-Job -Command { Install-WindowsFeature -ConfigurationFilePath
$ using:ConfigurationFilePath -ComputerName $ using:ComputerName -Restart } } Receive-Job -Job $ jobs -Wait | Select-Object Success, RestartNeeded, ExitCode, FeatureResult }
Then after this he states it is going to want a few parameters, for example.
# Sample Invocation $ ServerNames = 'TestServer_01', 'LabServer_02' Invoke-WindowsFeatureBatchDeployment -ComputerNames $ ServerNames -ConfigurationFilePath C:\ RemoteDesktopConfig.xml
