Using command output as message in msg

Hi.

I'm trying to use the output of a Powershell commands as the content of a message in msg.

if I do:

$TEST = 123
msg /server:mypc * "$TEST"

I get the message box saying "123"

However, when I do:

$TEST = (cmdlet|cmdlet|cmdlet)|out-string
msg /server:mypc * "$test"

It dose not work.

Is there a way sent the output of (cmdlet|cmdlet|cmdlet)|out-string with msg?

Thank you! :)
