Hello, I am relatively new to Ignition and I have gone through the Induction University, I am currently working on the Ignition Design Challenge and I am at the Alarm Notification Pipeline section of the challenge. I am attempting to build an alarm notification pipeline that will send an email notification to notify two rosters of people on the active status of 3 alarms being triggered. Roster Admin/Manager will be notified on alarm activation of a cleaning status tag and roster roasters will be notified on alarm activation of a temp High/Low tag. While I could just build two separate pipelines one associated with the status tag and one for the high/low tag I am trying to have it built in one pipeline. My current format is Start into a switch block with an If expression to direct the active alarm to the proper notification block. I was curious if I should be formatting this pipeline differently or if I should use a different expression code as it currently isn't working as expected. I am new to the coding aspect and havent found any useful info online so I figured id try my luck here.
