Train Welding Humanoids Issues

Help and Feedback Scripting Support
#1

I am currently scripting the script that welds to the part when the anchor is off for the train system. It worked and welded but there is error.

The script for control

				local Weld = descendant
				Weld:Destroy()
			end

If possible, please explain me why.

Basically it isn’t finding the player and then your trying to access the .Name property of something that isn’t there that is why it’s not working, also why exactly are you checking if the player’s name exists?
