pointshop 2

[crooksy80]

hello im having problems with pointshop 2. I am not sure if it is a problem or its something ps2 does not have. everything works fine as far as models and all that go but i dont know how to add knifes to the shop i tried making a folder in ps2 called "weapons" and put the usual code in there "ITEM.Name = 'MewButterfly'
ITEM.Price = 20000
ITEM.Model = 'models/weapons/w_csgo_mewbutterfly2.mdl'
ITEM.WeaponClass = 'csgo_butterfly_mew'
ITEM.SingleUse = false

function ITEM:OnEquip(ply)
    ply:Give(self.WeaponClass)
    ply:SelectWeapon(self.WeaponClass)
end

function ITEM:OnHolster(ply)
    ply:StripWeapon(self.WeaponClass)
end"

But there has been no joy :/ is there something or a folder im missing im just not sur. Thanks!
