Hi, what he means is that you upload your script file (.gh file) to the forum so that people can open the file in their computers. Just attach it in your original post (by editing it) or in a new reply to this discussion.
Note that if you are using referenced geometry from Rhino, you will need to “internalize it” inside Grasshopper or also upload the Rhino file (.3dm) that the GH script is using.
You can internalize geometry by right clicking on a component and click on “internalize”
