Hi,

I’m attempting to run a script in an expression tag and face with an error below, how ever if I run the script on a button or run it from shared script it works fine. I’m not passing any parameters through this function as I try to figure out the why I’m unable to call it from the tag.

Expression tag:

```auto
runScript("project.BlndrNatSet.BlndrNatSet()",1000)
```

Script:

`def BlndrNatSet():
	natset=0
	return natset`

Tags are global to the gateway, so any expression they use can only access global (shared) resources.
