Shop with seller with a bug i cant fix even with no problems on output

[chavalquepro (BelligolBelligol)]

I wanna make a store with a seller where if you click e to a prompt a gui opens and you can buy weapons with points and also with datastore save

The gui can open but when i click the button to buy a item i dont get on the backpack and also the points doesnt subtracts

this is the script of Prompt_Tienda

local MostrarTienda = rs:WaitForChild("MostrarTienda")

print("hi")
prompt.Triggered:Connect(function(jugador)
print("hi")
	MostrarTienda:FireClient(jugador, prompt:GetAttribute("item_type"))
print("hello")
end)

this is the script of Compras

print("ComprarItemALPrinicipio si que funciona che")

local rs = game:GetService("ReplicatedStorage")

local ComprarItem = rs:WaitForChild("ComprarItem")
local MostrarTienda = rs:WaitForChild("MostrarTienda")
local NombreMoneda = rs:GetAttribute("moneda")
print("Hi")
function Comprar(jugador, item_id, item_type)
print("comprar funcion anda")
	for i, item in pairs(rs.Items:GetChildren()) do
		print("El lopp funciona correctamente")

		if item:GetAttribute("item_id") == item_id then
			local dinero = jugador.leaderstats[NombreMoneda]
			local precio = item:GetAttribute("precio")
			print(typeof(dinero.Value))
			print(typeof(precio))
			if dinero.Value >= precio then
				dinero.Value = dinero.Value - precio
				print("hi againxd")
				local it = item:Clone()
				item.Parent = jugador.Backpack
				print("this should work")

				
				MostrarTienda:FireClient(jugador, item_type)
				
			end
		end
	end
end
print("hiii")
ComprarItem.OnServerEvent:Connect(Comprar)

this is tienda gui script

local rs = game:GetService("ReplicatedStorage")
local NombreMoneda = rs:GetAttribute("moneda")

print("hola")
local MostrarTienda = rs:WaitForChild("MostrarTienda")
local jugador = game.Players.LocalPlayer
local gui = script.Parent


function Abrir(item_type)
print("tienda_gui funciona")
local saldo = gui.Main.Footer.Saldo
saldo.Text = jugador.leaderstats[NombreMoneda].Value

local items = gui.Main.Items
	for i, itemGui in pairs(items:GetChildren()) do
		if itemGui:IsA("Frame") then
			itemGui:Destroy()
		end
	end
print("Hi")

	for i, item in pairs(rs.Items:GetChildren()) do
		if item:GetAttribute("type") == item_type or item_type == "todos" then
			local itGui = rs.gui.Item:Clone()
itGui.Imagen.Image = item.TextureId
itGui.Info.Titulo.Text = item.Name
itGui.Info.Precio.Text = item:GetAttribute("precio").." G"
itGui.Parent = items
print("hola")
itGui:SetAttribute("item_id", item:GetAttribute("item_id"))
itGui:SetAttribute("item_type", item_type)
		end
		
	end

print("hi again")
gui.Enabled = true
end



MostrarTienda.OnClientEvent:Connect(Abrir)

this is comprar_item script

local boton = script.Parent
local itGui = boton.Parent
local rs = game:GetService("ReplicatedStorage")
local ComprarItem = rs:WaitForChild("ComprarItem")
print("hi1")
boton.MouseButton1Click:Connect(function()
	print("comprar_item funciona")
	ComprarItem:FireServer(itGui:GetAttribute("item_id"), itGui:GetAttribute("item_type"))
	print("2do comprar item")
end)

theres also attributes on the items ( each one has the same attributes else replicatedstorage)

this is replicated storage attributes ( moneda is the name of the coin = points)

this is the item attributes ( precio is price of the item)

there also remote events on ReplicateDStorage

now the locations of the scripts

ALSOOO the prompt ( where you touch the e to open the gui) has a attribute of item_type so it appears which type of items should it sell ( in this case are armas = weapons)

hope someone can help me fix this bug please
