I'm trying to create a script that can shutdown your computer. But i need some help.

Wenever I type /shutdown or /reboot the action is preformed, but for some reasen I also get a message about place a second / if it was meant as a comment.
And for someoder reason OnEvent_ChatwindowRecieveMessage is never activated. Neither with or without one of the commands.

Is there sombody that sees the bug?
Code benead here.

code:
