SWEPS and global variables

[Piratemilk]

Hi, Im trying to make a gun that can carry a global variable, as well as change it, right now this is what it looks like:

SWEP.Spawnable			= true
SWEP.AdminOnly			= true
SWEP.UseHands			= true

SWEP.ViewModel			= "models/weapons/c_pistol.mdl"
SWEP.WorldModel			= "models/weapons/w_pistol.mdl"

SWEP.Primary.ClipSize		= -1
SWEP.Primary.DefaultClip	= -1
SWEP.Primary.Automatic		= false
SWEP.Primary.Ammo			= "none"

SWEP.Secondary.ClipSize		= -1
SWEP.Secondary.DefaultClip	= -1
SWEP.Secondary.Automatic	= false
SWEP.Secondary.Ammo			= "none"

SWEP.Weight				= 5
SWEP.AutoSwitchTo		= false
SWEP.AutoSwitchFrom		= false

SWEP.PrintName			= "Gun"			
SWEP.Slot				= 3
SWEP.SlotPos			= 1
SWEP.DrawAmmo			= false
SWEP.DrawCrosshair		= true
SWEP.UseHands			= true

local VAR

function SWEP:Initialize()
	VAR = false
end

function SWEP:PrimaryAttack()
       print(VAR)
end

function SWEP:SecondaryAttack()
	if(SERVER) and !VAR then VAR = true end
	if(CLIENT) then VAR = true end
	print("look ", VAR)
end

function ZoomView(ply, pos, angles, fov)
        if VAR then
               print("happy")
               VAR = false
        end
end

hook.Add("CalcView", "ZoomView", ZoomView)

As you can see I have no idea what im doing, I've tried a number of things and cant seem to really get any results.

Heres some example output if I press mouse1, mouse 2, mouse 1.

false
look true
false

if I throw a print(VAR) at the beginning of ZoomView it prints nil; can anyone give me some advice on what Im doing wrong? do I have to use a usermessage or something? Shouldnt all of this data be shared? I really havent the faintest clue why this doesnt work.

You are setting the variable on client, but not server, that's your problem. You gotta use net library for this.

Is there a way for a client to carry their own global values or is that completely impossible? I saw some ConVar client command, but it looks like its static; is a dynamic global variable only possible via server side?
