Hello Team,

Finding difficulty to write correct syntax during creation of exception. Color indication should be showed based on the below condition.

If incident created between 0-8 Hours color should "GREEN" and when incident created between 8-16 hour than color should be "YELLO" and when incident created between 16-24 hours color should be "RED" but priority is "NORMAL"

If incident created between 0-2 Hours color should "GREEN" and when incident created between 2-4 hour than color should be "YELLO" and when incident created between 4-8 hours color should be "RED" but priority is "Urgent"

Please refer the screen shot you will have complete idea what exactly I am looking for.
