I'm experimenting with Powershell to add a ClusteredScheduledTask on a clustered server (Win 2012/R2)

Technet sample code gives error:

#canned exampled from http://technet.microsoft.com/en-us/library/jj649815.aspx
$Action01 = New-ScheduledTaskAction -Execute Notepad
$Action02 = New-ScheduledTaskAction -Execute Calc
Set-ClusteredScheduledTask -TaskName "Task03" -Action $Action01,$Action02

Error:

Set-ClusteredScheduledTask : Incorrect function.

At I:\Scripts\TaskSchedulerSetupJobs\TestWebSampleCode.ps1:4 char:1

    + FullyQualifiedErrorId : HRESULT 0x80070001,Set-ClusteredScheduledTask

Added: As KrisFR pointed out below, I really meant to do a Register, not Set, but I still get the same basic error:

#canned exampled from http://technet.microsoft.com/en-us/library/jj649815.aspx
