Hi, something is wrong:
I activated the script with the following variables:
var keywords = ["bank","vault","banker","balance"]; // you can add your name/nickname here
var usePopup = true; // set to false if you don't want a popup
var useSound = false; // set to false if you don't want a ding
var useNotifications = true; // set to false if you don't want notifications

If I am in chat, it colors the messages with keywords yellow, I don't receie a popup and no notification though. What do I do?
