New Problem with my code

Hi there is a problem with my code when I place down 2 computers the robot doesnt move to the other one. all variables are right anyone have a solution??

local seat = nil
spawn(function()
	while wait(4) do
		while script.Parent.Humanoid.Sit == false do
			local Closest = nil

			local ClosestDis = math.huge
			for i,v in pairs(script.Parent.Parent:GetDescendants()) do

				if v.ClassName ~= "Seat" then continue end
				v:GetPropertyChangedSignal("Occupant"):Connect(function()
					local s, e = pcall(function()
						local person = v.Occupant 
						if person.Parent == script.Parent then
							seat = v
						end
					end)

				end)
				game.Workspace.DescendantRemoving:Connect(function(h)
					if h == seat then
						script.Parent.Humanoid.Sit = false
					end
				end)
				--if not Closest then Closest = v end

				if Closest ~= nil and (Closest.Position - v.Position).Magnitude < ClosestDis and Closest.Parent.Parent.Parent:FindFirstChild("Multi") and not Closest.Occupant then
					warn(Closest)
						Closest = v
						ClosestDis = (Closest.Position - v.Position).Magnitude
				else
					local s, e = pcall(function()
						warn("no seat found")
						print(Closest.Occupant)
						print(Closest.Parent.Parent.Parent:FindFirstChild("Multi"))
					end)


				end
			end
			if Closest ~= nil then
				script.Parent.Humanoid:MoveTo(Closest.Position)
				wait(5)
				if script.Parent.Humanoid.Sit == false then
					script.Parent.HumanoidRootPart.CFrame = Closest.CFrame
				end
			end
		wait(1)

	end


	end


end)

spawn(function()
	while true do
		repeat wait(0.05) until script.Parent.Humanoid.Sit == true
		script.Parent.Head["Audio/keyboard typing"]:Play()
		anim = script.Parent.Humanoid:LoadAnimation(script.Parent.Humanoid.Animation)
		anim:Play()
		repeat wait(0.02) until script.Parent.Humanoid.Sit == false
		anim:Stop()
	end

end)
