Lua Error in Pointshop

[spocksgirl94]

I keep getting this lua error but I don't understand why.

[ERROR] addons/pointshop-master/lua/items/playermodels/marty.lua:19: attempt to call global 'AddPlayerModel' (a nil value)
  1. unknown - addons/pointshop-master/lua/items/playermodels/marty.lua:19
   2. include - [C]:-1
    3. LoadItems - addons/pointshop-master/lua/sh_pointshop.lua:105
     4. unknown - addons/pointshop-master/lua/autorun/pointshop.lua:35

Anyone know why?

Post the code.

ITEM.Name = 'Marty'
ITEM.Price = 10000
ITEM.Model = 'models/player/mart.mdl'

function ITEM:OnEquip(ply, modifications)
	if not ply._OldModel then
		ply._OldModel = ply:GetModel()
	end
	
	timer.Simple(1, function() ply:SetModel(self.Model) end)
end

function ITEM:OnHolster(ply)
	if ply._OldModel then
		ply:SetModel(ply._OldModel)
	end
end

AddPlayerModel( "marty", "models/player/mart.mdl" )

Remove the AddPlayerModel line. I can't find anything on the net where that function is from.
