Workspace.H:7: attempt to concatenate Instance with string

Code:

game.ReplicatedStorage.MapFuncs.TweenPart.Event:Connect(function(thing222, x2, y2, z2, spped)
        local x33333333333 = thing222.Position.X + x2
    local y3333 = thing222.Position.Y + y2
    local z33333333 = thing222.Position.Z + z2
    game.ReplicatedStorage.ConsoleLog:Fire("Tweening "..thing222.." with "..z33333333..","..y3333..","..x33333333333.." at "..spped.."s")
    wait()
    local TweenService = game:GetService("TweenService")
local thing = thing222
local tweeening = TweenInfo.new(    
    spped,
    Enum.EasingStyle.Linear,
    Enum.EasingDirection.Out,
    0, 
    false,
    0
    )

local up = {CFrame = CFrame.new(x, y, x)}
local tweenup = TweenService:Create(thing,tweeening,up)

tweenup:Play()

end) 

and yes everything else is proper it's actually line 5
