How to fix this problem with my region3 not detecting more than one player?

local TablePlayers = {}
while wait(1) do
local regionPart = game.Workspace.Zone

		local pos1, pos2 = (regionPart.Position - (regionPart.Size / 2)), (regionPart.Position + (regionPart.Size / 2))
		local region = Region3.new(pos1, pos2)
local partsInRegion = workspace:FindPartsInRegion3(region)

for i, Entity in pairs (partsInRegion) do
	if (Entity.Parent:FindFirstChildOfClass("Humanoid")) and (Entity.Parent:FindFirstChildOfClass("Humanoid").Health > 0) and Entity.Parent:FindFirstChild("Values") and not Entity.Parent:FindFirstChild("NPC") then
	local player = game.Players:GetPlayerFromCharacter(Entity.Parent)
	Entity.Parent.Values.AreIn.Value = true
	table.insert(TablePlayers,player)
	end
	end
	for _,plr in pairs(game.Players:GetChildren()) do
	local character = plr.Character or plr.CharacterAdded:Wait()
	if not table.find(TablePlayers,plr) then
	character.Values.AreIn.Value = false	
		end
		end
	TablePlayers = {}
	end
