Moving GUIs, But isn't returning to they respective positions, why?(solved)

Hello Helpers!

I'm trying to move an ImageButton to a certain position, the problem is that I can not make it to return to it starting position every time when I click to another ImageButton

I wanna put the current ImageButton(Obj2).position to a table and make it return to they original position whatever i click to a not equipped GUI

local Empty = false
local Positions = {}
for i,Obj2  in pairs(Gui.Frame:GetChildren())
    table.insert(Positions,Obj2.Position.X and Obj2.Position.Y)

        Obj2.MouseButton1Down:connect(function()                            
        if Empty == false and Obj2.IsEquipped.Value == false then
        Obj2:TweenPosition(UDim2.new(0.5,-35,1,-70), "Out", "Quad",1) -- equip position
        Obj2.IsEquipped.Value = true
        player.Character.Humanoid:EquipTool(v)
        wait(1)

        elseif Obj2.IsEquipped.Value == true then
        Obj2:TweenPosition(UDim2.new(Positions[i]), "In", "Quad",1) -- it's not returning to the original position
        player.Character.Humanoid:UnequipTools()
        wait(1) 
        Obj2.IsEquipped.Value = false
        end                     
    end)
end

it's moving the ImageButton to position (0,0,0,0) and not to the original position, after the change :(

Sorry, English isn’t my first language.
