How to stop a notification being sent again when a ticket is updated

How to stop a notification being sent again when a ticket is updated

Hi,

I have a business rule setup to send a notification to the requester when a fields is selected to advise them of the status of an application. The issue I am having is that when the support rep goes into the ticket and updates another field (while leaving the field that is driving the business rule the same), it send the notification again. Is there a way of being able to leave this filed the same and update other fields without the notification being sent again.


Thanks


I have attached the business rule.
