Create an entity with price based on player parameter

[Sachha]

Hi,

I'm French so sorry for my English :/

Well, i want to create an entity (MoneyPrinter) with a price and a amount given money based on a player parameter like money (but in fact it's level).

For exemple, if the player had 300$, the moneyprinter will cost 30$ and give 3$
If he had 500$, the moneyprinter will cost 50$ and give 5$

It's possible ?

I try that but that didn't work =>

local ply = LocalPlayer()
local Printer={}
Printer.Name = 'MoneyPrinter'
Printer.Type = 'printer'
Printer.XPPerPrint = 50*ply:getDarkRPVar('level')
Printer.MoneyPerPrint = 50*ply:getDarkRPVar('level')
Printer.Color = Color(255,255,255,255)
Printer.Model = 'models/props_lab/reciever01b.mdl'
Printer.Price = 500*ply:getDarkRPVar('level')
Printer.Level = 1*ply:getDarkRPVar('level')
Printer.Prestige = 0

table.insert(Printers,Printer)

That say ply send a nil and i understand why but how to do for what i want ?

Thanks for reading
