[ERROR] lua/weapons/gdcw_intervention/shared.lua:133: 'end' expected (to close 'function' at line 80) near '<eof>'
1. unknown - lua/weapons/gdcw_intervention/shared.lua:0

Hello. So i Return to this corner and some of you will remember me - two errors i get with the sniper i have.

And the first 3 lines from line 1 is:

(blank line)
SWEP.Category				= "BBB Community Weapons"
SWEP.Author				= "Sir. Abyssal2001 / Sir. Braden1996"

The starting is line 79, and the ending is line 132

function SWEP:SecondaryAttack()
    if not self.IronSightsPos then return end
    if self.Weapon:GetNextSecondaryFire() > CurTime() then return end

    bIronsights = not self:GetIronsights()

    self:SetIronsights( bIronsights )

if CLIENT then
   local scope = surface.GetTextureID("sprites/scope")
   function SWEP:DrawHUD()
      if self:GetIronsights() then
         surface.SetDrawColor( 0, 0, 0, 255 )

         local x = ScrW() / 2.0
         local y = ScrH() / 2.0
         local scope_size = ScrH()

         local gap = 80
         local length = scope_size
         surface.DrawLine( x - length, y, x - gap, y )
         surface.DrawLine( x + length, y, x + gap, y )
         surface.DrawLine( x, y - length, x, y - gap )
         surface.DrawLine( x, y + length, x, y + gap )

         gap = 0
         length = 50
         surface.DrawLine( x - length, y, x - gap, y )
         surface.DrawLine( x + length, y, x + gap, y )
         surface.DrawLine( x, y - length, x, y - gap )
         surface.DrawLine( x, y + length, x, y + gap )

         local sh = scope_size / 2
         local w = (x - sh) + 2
         surface.DrawRect(0, 0, w, scope_size)
         surface.DrawRect(x + sh - 2, 0, w, scope_size)

         surface.SetDrawColor(255, 0, 0, 255)
         surface.DrawLine(x, y, x + 1, y + 1)

         surface.SetTexture(scope)
         surface.SetDrawColor(255, 255, 255, 255)

         surface.DrawTexturedRectRotated(x, y, scope_size, scope_size, 0)

      else
         return self.BaseClass.DrawHUD(self)
      end
   end

   function SWEP:AdjustMouseSensitivity()
      return (self:GetIronsights() and 0.2) or nil
   end
end

put an "end" before "if CLIENT then"
