Actions and Tasks in ODM

Hello,

I have a problem executing a PowerShell script inside ODM (as example, I only want to create a folder underneath c:\temp, like testfolder1. When I create the task and press the "Load Script Framework" button, it will load the two standard lines. Because there is not really documentation available regarding this feature - what shall I do here? In the Param section I put in nothing. And then I tried to put my two line of PS code between $output.... and return(§output). When I then try to execute (queuing), then I got the message "no command were given for device. Failed to queue jobs for [x] device. I understand the message, but how I can provide the command to execute the script?
