Creating a custom Alert in Data Quality

Hi ,
I’m trying to create a custom Alert in Data Quality in my dataset called “ALERT_LAB_DISHWASHERS.CYCLE_DATA” to trigger an Alert if the field HOT_WATER_TEMP_VALUE <= 85 (this is entered as the condition); but I’m not receiving the Alert Email.
When I entered score <101 as the condition, it worked and I received the Email.
Please let me know what I’m doing wrong

Thank you
Bob
