You could use a client event script tag change event handler to monitor the tag(s) for changes.

If you want to pop it up for any alarm, then I would create a memory expression tag that called `system.alarm.queryStatus` to count alarms in the folder it’s in, and monitor tag change events on that tag.

This is the UDT that I use to count alarms within a folder (and its subfolders) :  
[Area Alarms.xml](https://forum.inductiveautomation.com/uploads/short-url/2cPNho1YGklVImONAJk4izd2Gqb.xml) (1.2 KB)  
You can just place it in the root tag folder to count all alarms

No worries. Not sure if you saw, but I edited my post above and added a udt xml to it
