the problem is here:
var Message == "Hello " + Messenger.MyName + "(Smilie)";
MsgPlus.DisplayToast("", Message, "notify.wav");
it needs to be:
var Message = "Hello " + Messenger.MyName + "(Smilie)";
MsgPlus.DisplayToast("", Message, "notify.wav");
"==" is used to see if two things are already equal. "=" is used to make one thing equal to another.
some times your request for help gets lost in the sea of other requests
hope that helps!
