I want to make a zombie that follows you , but isnt working. What is wrong with the script?

the script is a local script and its located in the zombie's humanoid

local i = game.Players.LocalPlayer
local e = i.Character
while true do
	if (e.Torso.Position - script.Parent.Parent.Torso.Position).magnitude <30 then
		script.Parent.WalkToPoint = e.Torso.Position
	else
		break
	end
end

I think you should use a server script instead of a local script since this only follows the local player? On the server script, you could get the closest player to the zombie or a targeted player and make the zombie follow them.
