[ccnet-user] error MSB4067: The element <script> beneath element <powershell> is unrecognized.

[Mark]

I'm working to get my builds on CC.NET 1.6.x running on my Win2k8R2
server.

I'm trying to use the new powershell call.  And I get the error as
noted in the subject line.

Anyone have a clue what I've done wrong?  Most of this I copied
directly from the 
http://confluence.public.thoughtworks.org/display/CCNET/PowerShell+Task
site.
