Your entry looks ok, aside from the missing closed curly bracket and comma }, that should appear at the end, after the last curly close bracket in your post above.
One question, are you sure about that updateInterval: 1500,? That’s only 1.5 seconds before a new compliment will appear. The default fade speed for the module is 4 seconds, so your compliments are fading well before they even appear.
Try updateInterval: 30000, - That’s 30 seconds
