Why isn't my scope showing up?

[??????]

Im making a sniper but the scope material doesn't seem to show up. I've narrowed it down to that the hudDraw function doesn't get updated that IsScope is true. Here is most of my code.[lua]IsScoped = false
SWEP.HoldType = "ar2"
SWEP.Base = "weapon_cs_base"
SWEP.Category = "Dave's Zombie Guns"

SWEP.Spawnable = true
SWEP.AdminSpawnable = true

SWEP.ViewModel = "models/weapons/v_snip_scout.mdl"
SWEP.WorldModel = "models/weapons/w_snip_scout.mdl"

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

SWEP.Primary.Sound = Sound( "weapons/scout/scout_fire-1.wav" )
SWEP.Primary.Recoil = 0.75
SWEP.Primary.Damage = 90
SWEP.Primary.NumShots = 1
SWEP.Primary.Cone = 0.01
SWEP.Primary.ClipSize = 5
SWEP.Primary.Delay = 1
SWEP.Primary.DefaultClip = 25
SWEP.Primary.Automatic = false
SWEP.Primary.Ammo = "xbowbolt"

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

function SWEP:Precache()
util.PrecacheSound( Sound( "weapons/scout/scout_fire-1.wav" ) )
end

function SWEP:SecondaryAttack()

if( !IsScoped) then

if(SERVER) then
self.Owner:SetFOV( 25, 0 )
end
scope()
IsScoped = true

else

if(SERVER) then
self.Owner:SetFOV( 0, 0 )
end

IsScoped=false

end

end

function SWEP:Holster()

if(SERVER) then
self.Owner:SetFOV( 0, 0 )
end

IsScoped = false

return true
end

function SWEP:DrawHUD()
Msg(IsScoped)
if IsScoped then
local QuadTable = {}

QuadTable.texture = surface.GetTextureID( "overlays/scope_lens" )
QuadTable.color = Color( 255, 255, 255, 255)

QuadTable.x = 0
QuadTable.y = 0
QuadTable.w = ScrW()
QuadTable.h = ScrH()
draw.TexturedQuad( QuadTable )
end

end
