How to make two GUI's invisible after pressing a button?

I was creating a game and I’m trying to make two GUI’s in the same parent invisible.
Here’s the code: (look at explorer to see what I’m trying to do)

If you want to disable that ScreenGui, it’s a simple

script.Parent.Parent.Enabled = false

This script is working for me.

    local button = script.Parent

button.MouseButton1Click:Connect(function()
	game.Lighting.Blur.Size = 0
	script.Parent.Parent.Enabled = false
end)
