Counter strike crosshair problem for TTT

[monstermega10]

So recently i have found a gamemode that has the crosshair movement of counter strike and i tried moving it to weapon_tttbase. It works, but for some reason when trying to zoom in with a sniper, theres this glitch where there is no scope. It just zooms in.

This is what I have placed into the
funtion SWEP:Initialize()

--Spread Change
self:SetNWInt("crouchcone", self.CrouchCone)
self:SetNWInt("crouchwalkcone", self.CrouchWalkCone)
self:SetNWInt("walkcone", self.WalkCone)
self:SetNWInt("aircone", self.AirCone)
self:SetNWInt("standcone", self.StandCone)
self:SetNWInt("ironsightscone", self.IronsightsCone)
self:SetWeaponHoldType( self.HoldType )

and this is what I place in
SWEP:think()
which was empty at first and replaced it with

function SWEP:Think()

if self.Owner:OnGround() and (self.Owner:KeyDown(IN_FORWARD) or self.Owner:KeyDown(IN_BACK) or self.Owner:KeyDown(IN_MOVERIGHT) or self.Owner:KeyDown(IN_MOVELEFT)) then
if self.Owner:KeyDown(IN_DUCK) then
self.Primary.Cone = self:GetNWInt("crouchwalkcone")
else
self.Primary.Cone = self:GetNWInt("walkcone")
end
elseif self.Owner:OnGround() and self.Owner:KeyDown(IN_DUCK) then
self.Primary.Cone = self:GetNWInt("crouchcone")
elseif not self.Owner:OnGround() then
self.Primary.Cone = self:GetNWInt("aircone")
else
if (self:SetIronsights() == true) then
self.Primary.Cone = self:GetNWInt("ironsightscone")
else
self.Primary.Cone = self:GetNWInt("standcone")
end
end
