Why is :MoveTo() not working inside my Follow script??

I watched a video on zombie that can follow you. It uses MoveTo.

I have some printers reporting who the closest target is, and they appear perfectly, but the zombie never follows me, without an error in both studio and public. Is there a way to fix this?

SCRIPT

local torso = script.Parent.Torso
local h = script.Parent.Humanoid
local spawncf = script.Parent.Torso.CFrame


function findPlayer()
	for _,v in next,game.Players:GetPlayers() do
		if v.Character then
			local char = v.Character
			
			if char:FindFirstChild("Humanoid") and char:FindFirstChild("Torso") then
				local ptorso = char.Torso
				
				if (ptorso.Position - torso.Position).magnitude <= 20 then
					return v
				end
			end
		end
	end
	
	return nil
end

while wait() do
--	if findPlayer() ~= nil then
--		print(findPlayer().Name)
--	else
--		print("nil")
--	end
	
	local player = findPlayer()
	
	if player then
		h:MoveTo(player.Character.Torso.CFrame.p)
	else
		h:MoveTo(spawncf.p)
	end
end
