–Ignition 7.5.3 (b1163)/Win2k8 Server Enterprise on VMWare ESXi 5.0–

I know I must be missing something absurdly simple and would greatly appreciate any help from the forum!

I set up the following event script (gateway) to fire on appropriate tag changes:

```auto
import string
from app import CIP_Log #<-- also tried "import CIP_Log" and "import app"

strWho = event.tagPath.itemName

if string.find(strWho, "CIP2") >= 0: CIP_Start("CIP2")
elif string.find(strWho, "CIP3") >= 0: CIP_Start("CIP3")
elif string.find(strWho, "CIP4") >= 0: CIP_Start("CIP4")
elif string.find(strWho, "CIP5") >= 0: CIP_Start("CIP5")
elif string.find(strWho, "CIP6") >= 0: CIP_Start("CIP6")
elif string.find(strWho, "LACTA") >= 0: CIP_Start("LACTA")
```

which generates the following error:

```auto
Traceback (most recent call last):
  File "<TagChangeScript:UD_Datalogs/All_CIP_Start>", line 8, in <module>

```

In the Script Module Editor, I have one package, the default “app”, containing two scripts “CIP\_Log” and “Lookups”. The first few lines of CIP\_Log are:

```auto
def CIP_Start(strCIP_Unit):
	import system
	import datetime
	import app.Lookups
# --more code below--
```

… what am I missing? It shouldn’t be a scope issue…

What about trying something more like this (shouldn’t have to import app):

```auto
import string

strWho = event.tagPath.itemName

if string.find(strWho, "CIP2") >= 0: app.CIP_Start("CIP2")
elif string.find(strWho, "CIP3") >= 0: app.CIP_Start("CIP3")
elif string.find(strWho, "CIP4") >= 0: app.CIP_Start("CIP4")
elif string.find(strWho, "CIP5") >= 0: app.CIP_Start("CIP5")
elif string.find(strWho, "CIP6") >= 0: app.CIP_Start("CIP6")
elif string.find(strWho, "LACTA") >= 0: app.CIP_Start("LACTA")

```

I’m guessing by the way you’re importing that you’re trying to save yourself from having to write “app” over and over - so try this:

[code]import string  
from app import CIP\_Log

strWho = event.tagPath.itemName

if string.find(strWho, “CIP2”) \>= 0: CIP\_Log.CIP\_Start(“CIP2”)

# more code[/code]

Yeah, you still have to reference CIP\_Log each time, but at least it saves you from writing “app” for each function call. 😉
