I'm using the isAlarmActiveFiltered expression to determine if I have tags in alarm based on Display Name. For example, I have an expression tag called isAlarmMM01Dryer with the expression: `isAlarmActiveFiltered("*"`_`,"*"`_`,"MM01 Dryer",1,4,0,1,0)` - Boolean, Event Driven and it works, whether or not I have a tag with the "MM01 Dryer" display name in alarm is reflected as true or false and I have a 'Good' quality. I made a copy of that tag and named it isAlarmMM02 and changed the expression to `isAlarmActiveFiltered("*"`_`,"*"`_`,"MM02 Dryer",1,4,0,1,0)` and I get a quality status of "Bad\_NotFound". I checked my Display Names and they look correct. Does the Display Name in the expression have to exist on at least one tag? I don't currently have any tags in alarm but I still get good quality on 1 and bad on 2. ---

The third parameter filters for Display Path. So the first one is called `isAlarmMM01Dryer` and the second is called `isAlarmMM02`. Have you tried renaming the second one to `isAlarmMM02Dryer`? I can't guess what your entire setup looks like, but it looks odd not being an _exact_ copy (apart from the 1/2 change) ---

Sorry, typo on my part. The second tag is named 'isAlarmMM02Dryer'. The expression is copy-pasted between the two, the only difference is the 1/2. What I find odd is that it seems that even if I typed the Display Path name wrong, I would think the expression would evaluate to false. Can anyone confirm that? Is there any way to get more detail at the OPC level of why the quality is Bad\_NotFound? ---

I deleted the tag and recreated it from scratch instead of a copy/edit and it works
