No matter what i do to a(seemingly) simple script i'm trying as my first script it never runs! I've changed it based on every syntax error I can think of but it still won't run.

code:

---

function OnEvent_MyPsmChange(NewPsm)
{
    var psm = Messenger.MyPersonalMessage();
    ChatWnd.SendMessage("I changed my personal message to: " + psm);
}
