Killing processes on multiple machines remotely via powershell issue.

I am getting an error when trying to deploy the following code to multiple machines, see below.

Code:

$remote = new-pssession -computername teststation-2, teststation-1
import-pssession -session $remote -commandname *-process -prefix remote
get-remoteprocess -name fwt | stop-remoteprocess -force

Error:

Import-PSSession : Cannot convert 'System.Object[]' to the type 'System.Management.Automation.Runspaces.PSSession'
required by parameter 'Session'. Specified method is not supported.
