What am I doing wrong here? I have this global script that gets called by a gateway tag change script. what I am trying to add is the tag quality to the script, to verify that I have good quality before inserting a record. I am seeing duplicate records when a device loses comms so I figure that if I look at the quality before doing the insert, I should be ok. Ive tried doing “Good” and also 192, but neither work.

[code]def alarmChange(deviceName, newValue):  
import system, app

```
result = system.db.runPrepQuery("SELECT id FROM compdevices WHERE poll = 1 AND devicename = ?", [deviceName])

if len(result):
	deviceId = result[0][0]
	
	
	tagQuality = system.tag.getTagValue("%s/Comp_Stat.Quality" % (deviceName))
	if newValue == 1 and tagQuality == "Good":
		system.db.runPrepUpdate("INSERT INTO comphistory (compid, startalarmdate) VALUES (?, CURRENT_TIMESTAMP)", [deviceId])
	else:
		system.db.runPrepUpdate("UPDATE comphistory SET endalarmdate = CURRENT_TIMESTAMP WHERE compid = ? AND endalarmdate IS NULL", [deviceId])[/code]
```

Well, system.tag.getTagValue returns the tags value, which is a QualifiedValue (I think).

So you should be able to do:

```auto
tagQuality = system.tag.getTagValue("%s/Comp_Stat.Quality" % (deviceName)).quality
```

to get the quality.

You might also need to try doing it [this way.](http://inductiveautomation.com/forum/viewtopic.php?f=70&t=7386)

print the result of system.tag.getTagValue and see what you get, that might provide some insight.

It won’t put it where you can immediately see it.
