local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()

Sent = Player.Tier.Value
Player.Tier.Changed:connect(function()
Sent = Player.Tier.Value
end)

Mouse.Button1Down:connect(function()
	game.ReplicatedStorage.NewPointsToServer:FireServer(Player,Player.Tier.Value)
	print(Sent)
end)
