When I press the Buy button It wont subtract the price from the Players Cash. Can someone fix this?

This is my Buying Script I have all my variables set up correctly

game.Players.PlayerAdded:Connect(function(player)
	local Buy = player.PlayerGui:WaitForChild("Gui").Main.Info.Buy
	local leaderstats = player:FindFirstChild("leaderstats")
	local Cash = leaderstats:FindFirstChild("Cash")
	local price = player.PlayerGui:WaitForChild("Gui").Main.Info.Price
	local Gui = player.PlayerGui:WaitForChild("Gui").Main.Frame
	local Purchased1 = Gui.Item1.Purchased
	local Purchased2 = Gui.Item2.Purchased
	local Purchased3 = Gui.Item3.Purchased
	
	
	Buy.MouseButton1Click:connect(function()
		if Cash.Value >= price.Value then
		Cash.Value = Cash.Value - price.Value
		print("Yeet")
			if price.Value == 100 then
				local oldGun = player.Backpack:FindFirstChildOfClass("Tool") or player.Character:FindFirstChildOfClass("Tool")
				oldGun:Destroy()
				game.ReplicatedStorage.Tools.Pistol:Clone().Parent = player.Backpack
				Purchased1.Value = 1
			end
					if price.Value == 300 then
				local oldGun = player.Backpack:FindFirstChildOfClass("Tool") or player.Character:FindFirstChildOfClass("Tool")
				oldGun:Destroy()
				game.ReplicatedStorage.Tools.Revolver:Clone().Parent = player.Backpack
				Purchased2.Value = 1
					end
					if price.Value == 500 then
				local oldGun = player.Backpack:FindFirstChildOfClass("Tool") or player.Character:FindFirstChildOfClass("Tool")
				oldGun:Destroy()
				game.ReplicatedStorage.Tools.Uzi:Clone().Parent = player.Backpack
				Purchased3.Value = 1
					end
				end
			end)
		end)
