[Ricky Servietsky]

Hi,

attempt to call method 'RemoveCallback' (a nil value)

full code if needed :
function SWEP:PrimaryAttack()
  if not IsFirstTimePredicted() then return end
  self:Initialize()

end

function SWEP:SecondaryAttack()
  if not IsFirstTimePredicted() then return end
  self:RemoveCallbackZ('bbpcbid')
end

function SWEP:RemoveCallbackZ( varIndex )
  if CLIENT then
    self.Owner:RemoveCallback("BuildBonePositions", self.Owner:GetTable()[varIndex])
    self.Owner:SetVar(varIndex, nil )

  end

  if SERVER then
    print(self.Owner)
    print(varIndex)
    self.Owner:RemoveCallback("BuildBonePositions", self.Owner:GetTable()[varIndex])
  end

end

function SWEP:DrawWorldModel()
return false
end

function SWEP:Deploy()
self.Owner:DrawViewModel(false)
end

function SWEP:Initialize()
  self:SetHoldType(self.HoldType)

    if not self.Owner:GetTable()['bbpcbid'] then
      print("no bbpcbid in player table, adding one")
      local callbackId = self.Owner:AddCallback("BuildBonePositions", function(entTarget)

        if not entTarget:IsValid() then self:RemoveCallbackZ(entTarget:GetTable()[('bbpcbid')]) return end

         local rightFoot = entTarget:LookupBone("ValveBiped.Bip01_R_Foot")
         local head = entTarget:LookupBone("ValveBiped.Bip01_Head1")
         local rShoulder = entTarget:LookupBone("ValveBiped.Bip01_R_Shoulder")
         local lShoulder = entTarget:LookupBone("ValveBiped.Bip01_L_Shoulder")

         local headPos,headAng = entTarget:GetBonePosition(head)
         local lShoulderPos,lShoulderAng = entTarget:GetBonePosition(lShoulder)
         local rShoulderPos,rShoulderAng = entTarget:GetBonePosition(rShoulder)

         entTarget:SetBonePosition(head, headPos + Vector(0,0,10), headAng)

      end )
      self.Owner:SetVar("bbpcbid", callbackId )
    end
end

Your server is not up to date.

My server is not up to date ? What do you mean ? RemoveCallback doesnt exist serverside but exist clientside ?
What should i do then, ask my provider ? (im hosted by gmchosting)

Update your server through your provider's method, or make a ticket with them. RemoveCallback was added in the July update.
