MQTT extension issues

     Can anyone please help me on the MQTT extension in Thingworx.

     I imported the MQTT extension on the marketplace and configured my thing accordingly.

     property name = temperature

     topic to subscribe = temp/random

These are the setting I did in the configuration section.

My broker is connected as IsConnected = true.

But the property I created (temperature) doesn't reflect the message received on the topic(temp/random).

Please help me out with this at the earliest......
