I think I am having the same issue

```auto
alarmEvents = system.alarm.queryStatus(displaypath =[event.source.parent.getComponent('AlarmHi').toolTipText.replace("\"","") + "*",event.source.parent.getComponent('AlarmLo').toolTipText.replace("\"","") + "*",event.source.parent.getComponent('AlarmHiHi').toolTipText.replace("\"","") + "*",event.source.parent.getComponent('AlarmLoLo').toolTipText.replace("\"","") + "*"],state=["ActiveUnacked","ClearUnacked"])

```

This above line works in some places but not others.

I get an error

```auto

The stacktrace is doing it’s best to tell you what’s wrong; one of the `toolTipText` properties is `None`, rather than an empty string, some of the time you’re calling your script. You could isolate your calls by spacing them out, which might help you get a more accurate line number for the error:

```auto
alarmEvents = system.alarm.queryStatus(
	displaypath =[event.source.parent.getComponent('AlarmHi').toolTipText.replace("\"","") + "*"
		, event.source.parent.getComponent('AlarmLo').toolTipText.replace("\"","") + "*"
		, event.source.parent.getComponent('AlarmHiHi').toolTipText.replace("\"","") + "*"
		, event.source.parent.getComponent('AlarmLoLo').toolTipText.replace("\"","") + "*"
	]
	, state=["ActiveUnacked","ClearUnacked"]
)

```

Or, you can break out the logic and more easily add a ‘safe’ substitution (Python’s `None` is a ‘false-ey’ value, and inline `or` will return the second value if the first is false):

```auto
def getFilter(component):
	return (event.source.parent.getComponent(component).toolTipText or "").replace('"', '') + '*'

components = ['AlarmHi', 'AlarmLo', 'AlarmHiHi', 'AlarmLoLo']

alarmEvents = system.alarm.queryStatus(displaypath =[getFilter(component) for component in components], state=["ActiveUnacked","ClearUnacked"])

```

Thanks Paul,

The second approach works.
