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
