Script's not working? supposed to randomly clone a specified object into workspace.

Okay, let's get this straight im new to .random. I don't understand how it works so could someone help me out here?

Output: 04:11:08.318 - 2 is not a valid member of Lighting 04:11:08.320 - Script 'Workspace.Script', Line 3 04:11:08.320 - Stack End

workspace.ChildAdded:connect(function(child)
	if child:findFirstChild("Humanoid") then
		for i,v in pairs(game.Lighting[math.random(1,#game.Lighting:GetChildren())]) do
			v.Parent = child
		end
	end
end)

math.random returns a random number between, in your case, 1 and the number of objects in lighting. The error is saying "2" is not something that is IN lighting

I propose the following solution, which should randomly select an object from a table of objects, returned by GetChildren()

In the case of the error you received, this script would instead return the second object found in lighting.

Since you are randomly selecting one object, you don't need a loop.

workspace.ChildAdded:connect(function(child)
	if child:findFirstChild("Humanoid") then
		local v = game.Lighting:GetChildren()[math.random(1,#game.Lighting:GetChildren())]
		v.Parent = child
	end
end)
