The shop for my surface gui will not work, could someone help?

So I added currency in my game and obviously, I need to add a shop, but why surface ui shop will not work and I do not know how to fix it. Please help.

Button Script:

script.Parent.MouseButton1Click:Connect(function()
	local player = game.Players.LocalPlayer
	local character = player.Character
	local humanoid = character.Humanoid
	print("R")
	if player.Values.Points.Value >= script.Parent.Parent.Price.Value then
		print("E")
		humanoid.Health = humanoid.Health + script.Parent.Parent.NumItem * 2
		print("K")
		script.Parent.Parent.NumItem = script.Parent.Parent.NumItem + 1
		local event = game.ReplicatedStorage.RemoteEvents.Event
		event:FireServer()	
		print("T")
		player.Values.Points.Value = player.Values.Points.Value - script.Parent.Parent.Price
	end
	
end)

Server Script:

local event = game.ReplicatedStorage.RemoteEvents.Event

event.OnServerEvent:Connect(function(player,Price)
	player.Values.Points.Value = player.Values.Points.Value - Price
end)
