OPMANAGER WORKFLOW not able to display the variable $displayName in Email action

OPMANAGER WORKFLOW not able to display the variable $displayName in Email action

Hello,

I  have created a Workflow that detects an alarm, sends email and clears the alert.
The Workflow works fine and the only issue is the mail format to send.
I have added all the variables ie $stringseverity, $strModTime,$message.
We have only an issue with the $displayName.
Subject is taking IP instead of Device Name and message is not taking at all.

Can you please help.



Thanks,
