My 'for loops' don't run, may i know why?

I'm trying to make a door, basic stuff. As i did i encountered that the conditions that i gave the 'for loops' aren't right but i don't understand, may somebody say why?

local range = 20
local sensor = script.Parent
local open = false

-- -38.5, 3.2, 151.7
-- to
-- -33.3, 3.2, 151.7

--[[
for _, spottedPlayer in pairs(allPlayers) do
			if spottedPlayer ~= player then 
				print(spottedPlayer.Name)
				local selfPos = char.HumanoidRootPart.Position
				local localPlayerPos = spottedPlayer.Character.HumanoidRootPart.Position
				
				if (localPlayerPos - selfPos).magnitude < range then
]]--


local moveDoor = function(state)
	if state == "open" then
		for i = sensor.Position.X, -33.3, -0.1 do
			print(i)
			sensor.Position = Vector3.new(i, sensor.Position.Y, sensor.Position.Z)
			print("Opening")
			wait(0.2)
		end
	else
		for i = sensor.Position.X, -38.5, 0.1 do
			sensor.Position = Vector3.new(i, sensor.Position.Y, sensor.Position.Z)
			wait(0.2)
		end
	end

	
end

local standby = function()
	local allPlayers = game.Players:GetPlayers()
	for i = 1, #allPlayers  do
		local playerPos = game.Workspace:FindFirstChild(allPlayers[i].Name).HumanoidRootPart
		if (sensor.Position - playerPos.Position).magnitude < range and not open then
			print("Open")
			moveDoor("open")
			wait(6)
			moveDoor("nope")
		end
	end
end

connection = game.Players.PlayerAdded:connect(function(Player)
	connection:disconnect() 
	wait(5)
	while true do
		standby()
		wait()
	end
end)
