In the Notification Block page in the manual it states that alarm event properties when using a calculated roster can be accessed in the script using:

value = event[“propertyname”]

I’ve tried accessing the Display Path of my alarms using:

stationNum = event[“displayPath”]

and it doesn’t seem to work. I’m trying to use the value as a parameter in a database query and if I replace the parameter with a static number value it works fine. If I try using it I get the error:

Roster ‘’ has no users, notification for 1 alarms will go undelivered.

Has anyone had any success with this? Has the format for accessing the properties changed and documentation is not up to date or am I just going about it all wrong? Thanks for any input.
