SWEP counted as nil value

[TehFr33Man]

Well, I'm trying to make my first weapon in Garry's Mod, and the strangest error appears that I can't seem to resolve.

It says "attempt to access global 'SWEP' (a nil value)"

I know that the code is probably a train wreck, and it's not finished, primarily because I want to test if I can actually fire it first, but here it is:

if SERVER then

		AddCSLuaFile ("shared.lua")
		
		SWEP.Weight = 5
		
		SWEP.AutoSwitchTo = true
		SWEP.AutoSwitchFrom = false
		
elseif CLIENT then

		SWEP.PrintName = "Silly Pistol"
		
		SWEP.Slot = 1
		SWEP.SlotPos = 1
		
		SWEP.DrawAmmo = false
		
		SWEP.DrawCrosshair = true
end

SWEP.Author = "Teh-Fr33Man"
SWEP.Contact = ""
SWEP.Purpose = "Mingebags clouding your server? Assassinate those asshats with this!"
SWEP.Instructions = "M1 to fire a single bullet. M2 to fire automatically."

SWEP.HoldType = "Pistol"
SWEP.FiresUnderwater = true
SWEP.Category = "Admin Essentials"
SWEP.base = "weapon_base"

SWEP.Spawnable = true
SWEP.AdminSpawnable = true
SWEP.AutoSwitchFrom = false
SWEP.AutoSwitchFrom = true
SWEP.ViewModel = "models/weapons/v_pist_usp.mdl"
SWEP.WorldModel = "models/weapons/w_pist_usp_silencer.mdl"
SWEP.ViewModelFOV = 90

//Primary Fire Variables
SWEP.Primary.ClipSize = -1
SWEP.Primary.DefaultClip = -1
SWEP.Primary.Automatic = false
SWEP.Primary.Ammo = "Pistol"
SWEP.Primary.TakeAmmo = 0
SWEP.Primary.Delay = 0
SWEP.Primary.Damage = 1000
SWEP.Primary.Recoil = 0
//Secondary Fire Variables
SWEP.Secondary.ClipSize = -1
SWEP.Secondary.DefaultClip = -1
SWEP.Secondary.Automatic = true
SWEP.Secondary.Ammo = "none"

local ShootSound = Sound("sound/weapons/tmp/tmp-1.wav")
function SWEP:Initialize()
	util.PrecacheSound(ShootSound)  
        self:SetWeaponHoldType( self.HoldType )
end 

function SWEP:Reload()
end

function SWEP.Think()
end

//SWEP Primary Fire
function SWEP:PrimaryAttack()
		if ( !self:CanPrimaryAttack() ) then return end
		local bullet = {}
			bullet.Num = 1
			bullet.Src = self.Owner:GetShootPos()
			bullet.Dir = self.Owner:GetAimVector()
			bullet.Spread = Vector( 0, 0, 0 )
			bullet.Tracer = 0
			bullet.Force = 1
			bullet.Damage = self.Primary.Ammo
			bullet.AmmoType = self.Primary.Ammo
		local rndb = self.Primary.Recoil * -1
		local rndb = self.Primary.Recoil * math.random (-1,1)
		self:ShootEffects()
		self.Owner:FireBullets( bullet )
		self.Weapon:EmitSound(Sound(ShootSound))
		self:TakePrimaryAmmo(self.Primary.TakeAmmo)
		self.Owner:ViewPunch( Angle( rnda,rndb,rnda ) )
		self.Weapon:SetNextPrimaryFire( CurTime() + self.Primary.Delay )
		self.Weapon:SetNextSecondaryFire( CurTime() + self.Primary.Delay )
end

It says the error takes place at line 5, but its probably throughout the whole script.
Any and all help appreciated.

Is the SWEP.Base set correctly? Is it referencing a real file?

Probably not, actually. I have very, very, very little knowledge of coding in general, let alone lua.

Ok, so when your working with SWEPS, you have to have the correct folder setup. Hopefully this helps some.
Ignore the fact that it's in winrar, I was just to lazy to unzip it to show you. You obviously wouldn't have your folders zipped up for Gmod.

Thanks. I'll try that.
