Alerting on universal poller

Hi there,

I used this article to create an alert for a custom poller, but it seems that the alert condition can't find any match.

This the trigger condition:

Trigger Condition:

Alert on all objects where:
Node - Machine Type - is equal to - Geist Manufacturing
The actual trigger condition:
All child conditions must be satisfied (AND)
Custom Poller - Unique Name - is equal to - SensorTemp
Custom Poller Current Stats - Current Value - is greater than - 0
Based on the Universal Device Poller builder, the poller name is SensorTemp
Any help to figure out what i'm missing here, is greatly appreciated.
