Grasshopper GH for Mac

Hi Robert McNeel and friends,
I have a problem with this script. The component “Field Line” could be not solved.
Could you please supply me with help?
I hope so!
All the best Liv Marie Rømer

i am not familiar with fields… but was curious…
when you make the Bounds bigger for the creation of the fields - it works.
the points you charge are outside the bounds

Thanks a lot Jakob. I tired to follow this tutorial and I was hoping to make it look like this. https://www.youtube.com/watch?v=Kl3zrDrXto8
I can’t figure out what is missing… maybe you can?
