I have a project library script that works when I call it from the script console but I can't get a `runScript()` expression to work with it, for whatever reason. I get correct results in the console and I'm calling the function the exact same way.

```python
runScript("Data.getCommodityOptionDataset('[default]Bins/Commodities', 21)")

```

Where is the `runScript` expression being used?

In that case, the project your library is defined in must be configured as the Gateway Scripting Project.

See [Project Library | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/platform/scripting/scripting-in-ignition/project-library#gateway-scripting-project)

Also, that's the legacy method of calling the runScript expression. New way would be something like:

```python
runScript('Data.getCommodityOptionDataset', 0, '[default]Bins/Commodities', 21)

```

Would be nice if there was a prompt on the gateway webpage after creating the first project asking if you would like to set the project as the gateway scripting project. I know I've had this happen before
