Guis dont work?

Hi, I have got a big problem, because i made script (spawner of car) and local script (wich is mading guis with buttons) Ok, let me first write source. Local script placed in StarterGui (Don't calling event (I think guis dont work but im not sure, i made all with guis good))

for _, i in pairs(game.Workspace:GetChildren()) do
    if string.sub(i.Name, 1, 6) == "Hangar" then
        local CustomCarSG = i.Script.SurfaceGuiC:Clone()
        CustomCarSG.Parent = script.Parent
        CustomCarSG.Adornee = i.SpawnerC
        CustomCarSG.TextButton.MouseButton1Click:connect(function() i.Script.SpawnCar:Invoke("Car", script.Parent.Parent.Name) end)
        local KBCarSG = i.Script.SurfaceGuiKB:Clone()
        KBCarSG.Parent = script.Parent
        KBCarSG.Adornee = i.SpawnerKB
        KBCarSG.TextButton.MouseButton1Click:connect(function() i.Script.SpawnCar:Invoke("CarKB", script.Parent.Parent.Name) end)
        local ToolSG = i.Script.SurfaceGuiT:Clone()
        ToolSG.Parent = script.Parent
        ToolSG.Adornee = i.SpawnerTools
        ToolSG.TextButton.MouseButton1Click:connect(function() i.Script.GiveItems:Invoke(script.Parent.Parent.Name) end)
        local CustomCarSG = i.Script.SurfaceGuiC:Clone()
        CustomCarSG.Parent = script.Parent
        CustomCarSG.Adornee = i.SpawnerC
        CustomCarSG.TextButton.MouseButton1Click:connect(function() i.Script.Spawn:Invoke("Car", script.Parent.Parent.Name) end)
    end
end

Script placed in Hangar model
