Lua scripting problem! Trying to edit bodygroups on playermodels (pointshop)

[BGH]

Ok, so I'm running a gmod Jailbreak 7 server, and I'm trying to be able to edit the bodygroups of a playermodel I have in Pointshop. Here is the .Lua I'm currently using. And I'm using this addon: [url]http://steamcommunity.com/sharedfile.../?id=546524865[/url]
I'm new to coding so most of the time I've no idea what I'm doing. So can someone pls help me!

ITEM.Name = 'Black Rock Shooter'
ITEM.Price = 1000
ITEM.Model = 'models/jazzmcfly/brs/brs.mdl'

function ITEM:OnEquip(ply, modifications)
if not ply._OldModel then
ply._OldModel = ply:GetModel()
end
timer.Simple(2, function() ply:SetupHands()
ply:SetModel(self.Model)
--ply:SetSkin(1)
ply:SetBodygroup(1, modifications.group1 or 0) --Hood
ply:SetBodygroup(2, modifications.group2 or 0) --Coat
ply:SetBodygroup(3, modifications.group3 or 0) --Bottom
ply:SetBodygroup(4, modifications.group4 or 0) --Flame
end)
