Yes, but your change in the `def` line broke it. The comment in the sample code for `tagFolder` indicates what the **caller** should supply.

No. That comes from the caller.

{ Seems to me you need to go through some python scripting basics. }

Sure, i'll could use some basic Python scripting...

I think the 1 and 2 arg is right? But I dont get the purpose of the 3.?

Of course, that makes sence, thanks, but i'll get this error.

You have enclosed your tag folder path in curly braces, which makes the expression attempt to read the path's value. You need to pass a string. If a constant, put it in quotes. If you have the string in a property, put the path to the property in curly braces.

{ Seems to me you need to go through some Ignition expression binding training. }

I'll stop here until I hear from you that you've completed IU.

I'll tried with quote also, but still error.

I have done some of the IU training, but I will do a lot more for sure.

Is there something wrong with script you made? Do I need to change anything but the columnTags?

Could be. Call it from the designer script console.

Thanks. How can I pass the tagfolder path to the script console?

And yes, I am reading articles and watching the videos on IU trying to understand this, but I'm really stuck here..

Don't put the sample code in the script console. _ **Call** _ the function from script console. One line:

```auto
ds = BrewfatherDatasetDropdown.getDatasetFromArrayTags("[default]Brewfather_OPCUA")

```

This will produce a more complete error for you (us) to see.

Have you saved the project since you created that script?

Yes, but I updated my comment above since I have changed the name of the script from "BrewfatherDatasetDropdown" to "BrewfatherDataset".

This is the correct error:

Replace `system.tag.toDataSet` with `system.dataset.toDataSet`.

One more thing, is there a simple way to not list the values if value is "-1" or "Ingen"? If not, I can manipulate the strings in PLC, but It would be nice if possible in ignition 🙂
