So, I am new to the Compellent/Powershell scene and decided that I would try to some simple Volume Folder creations. (We have 3 new units and I don't want to manually create every folder, volume, etc.).  I feel like I am running into a newb problem here, but I have banged my head long enough.

Here's the issue.  I can run:

New-SCVolumeFolder SCRIPT_TEST -Connection $conn

No problems, the folder is created and all is right with the world.  But if I try to get a little complicated:

New-SCVolumeFolder "Auto Tier" -ParentSCVolumeFolder SCRIPT_TEST -Connection $conn

I get this error:

Cannot bind parameter 'SCVolumeFolder'. Cannot convert the "SCRIPT_TEST" value of type "System.String" to type "SCCommandSet.SCObjects.SCVolumeFolder".

I get the same bind error if I try to run:

Remove-SCVolumeFolder SCRIPT_TEST -Connection $conn

This happens whether I enclose the folder name in quotes, or set a variable and pass the variable.  What am I missing?
