TTT tried to buy weapon his role is not permitted to buy

[DJ Bat]

currently not allowed to purchase TTT weapon from the shop. the code i have for the TTT config is

--- TTT config values

-- Kind specifies the category this weapon is in. Players can only carry one of
-- each. Can be: WEAPON_... MELEE, PISTOL, HEAVY, NADE, CARRY, EQUIP1, EQUIP2 or ROLE.
-- Matching SWEP.Slot values: 0      1       2     3      4      6       7        8
SWEP.Kind = WEAPON_EQUIP1

-- If AutoSpawnable is true and SWEP.Kind is not WEAPON_EQUIP1/2, then this gun can
-- be spawned as a random weapon. Of course this AK is special equipment so it won't,
-- but for the sake of example this is explicitly set to false anyway.
SWEP.AutoSpawnable = false

-- The AmmoEnt is the ammo entity that can be picked up when carrying this gun.
SWEP.AmmoEnt = ""

-- CanBuy is a table of ROLE_* entries like ROLE_TRAITOR and ROLE_DETECTIVE. If
-- a role is in this table, those players can buy this.
SWEP.CanBuy = { ROLE_TRAITOR }

-- InLoadoutFor is a table of ROLE_* entries that specifies which roles should
-- receive this weapon as soon as the round starts. In this case, none.
SWEP.InLoadoutFor = nil

-- If LimitedStock is true, you can only buy one per round.
SWEP.LimitedStock = true

-- If AllowDrop is false, players can't manually drop the gun with Q

SWEP.AllowDrop = true

-- If IsSilent is true, victims will not scream upon death.
SWEP.IsSilent = false

-- If NoSights is true, the weapon won't have ironsights
SWEP.NoSights = true

-- Equipment menu information is only needed on the client
if CLIENT then
   -- Path to the icon material
   SWEP.Icon = "VGUI/ttt/anaicon"

   -- Text shown in the equip menu
   SWEP.EquipMenuData = {
      type = "Weapon",
      desc = "Rip through your enemies with a torrent of flame."

   };
end

-- Tell the server that it should download our icon to clients.
if SERVER then
   -- It's important to give your icon a unique name. GMod does NOT check for
   -- file differences, it only looks at the name. This means that if you have
   -- an icon_ak47, and another server also has one, then players might see the
   -- other server's dumb icon. Avoid this by using a unique name.
   resource.AddFile("materials/VGUI/ttt/anaicon.vmt")
   end

Is there a clash somewhere that is not allowing the SWEP to be bought it is inside the T shop but cannot be bought.

What do you mean "cannot be bought?"
What does it say or do instead?
