Email notification issue , not showing anything in preview window

[vahini]

Hi All , 

Can someone help me with this email issue i am unable to resolve . 

Client asked me to create a new UI Action on Incident form called 'Convert to Task' , Clicking this button will convert a incident to TASK and all fields copied over to Task that got created . and in same request client asked me to add new status for 'Incident state field'  called  'Closed converted to task'  . when we click UI action then Incident is marked as Closed converted to Task and Task is generated . 

I created email notification to fire when incident state is 'Closed converted to task' , when i preview this notification nothing is in the  notification preview window as shown below , and email is not being fired when Inc is converted to Task . what am i doing wrong here ?

Could you try to remove the ${event.parm1} part from the mail content? When the preview screen is empty this means there is an error in your mail content or subject. Since your notification is triggered by a status update and not an event, I'm not sure if event.parm1 exists, which would cause an error.
