Please check if you have followed the following steps while adding the Timer Control on the page:-
In the
Timer Control dialog box:
In the
General section, enter a name and label for the control.
Under
Data Source, next to Failure Time Field, select the date-time field that represents the time when a milestone should be completed. For example, select the
First Response By field.
Next to
Success Condition, select a field to use to evaluate the success of the milestone, and then choose the condition that indicates success. For example, select the
First Response Sent field, and then select Yes to indicate the success criteria of the First Response metric. This setting is required.
Next to
Warning Condition, enter the condition that will cause the timer control to display a warning when the time is about to expire. For example, in the first list next to
Warning Condition, select First Response SLA Status. In the list to the right, select
Nearing Noncompliance.
