I want to use isAlarmActiveFiltered inside a UDT to have a tag ON if any alarm inside the instance of the UDT have a high alarm.

I cannot make it work and the issue seems to come from the path.

This is not working:

isAlarmActiveFiltered({PathToParentFolder},"\*","_Waste_",3,3,0,0,0)

But this is working

isAlarmActiveFiltered("\*","\*","_Waste_",3,3,0,0,0)

Someone can help me?

we use something like:

```python
isAlarmActiveFiltered(concat(tag(concat("[.]../../",{InstanceName},".path")),"/*"), "", "", 1, 1, 0, 1, 0)

```

to gather all the alarms inside a folder of udt

This is probably what you want, go up one folder then search.

```python
isAlarmActiveFiltered("[.]../*", "*", "Waste", 3, 3, 0, 0, 0)

```
