Can event parameters be used inside messaging notification content?

[Colin6]

I have a requirement to send a notification to a Slack channel when an event is encountered. Some details which should be included in the notification are in the event parameters, so I'm trying to determine if there's a way to parse these for use inside "messaging content" as opposed to an email notification. So far I haven't had much success, as using ${event.parm1} or ${event.parm2} inside messaging content causes the notification to fail completely.

Could you post a screen of the content?

It should work inside the notification message content.

All I have in the message is "${event.parm1}" for troubleshooting purposes, but if I trip this notification with that in the message it doesn't get sent. Notifications are sent if I only put plain text in the message.
