Why the button inside of a Frame can't open a Frame?

I'm putting a custom face frame inside another frame so that players can put faces like in those games, when I put the script inside the button image: script.Parent.MouseButton1Click: Connect (function () game.ReplicatedStorage.Events.FaceEvent2: FireServer () end) The face frame does not become visible, I have the folders with Remote Event in Replicated Storange and they do not work, I used another graphical interface for the user, I arrange it and it stops working, but if I put it outside the same Gui as it came it works again before, but I want the Custom Faces frame to be visible within another frame. Here I show you a link of the graphical user interface that I am making! I hope you can help me with my question.

Here i put a link of the Archive .Zip that contain an Image of the Gui that I'm Making for my Fantasy Roleplaying Game: https://www.mediafire.com/file/v9bc25tu6invly0/Faces_Frame_Issues.zip/file

script.Parent.MouseButton1Click:Connect(function()
	if script.Parent.Parent.Background.Visible == false then
		script.Parent.Parent.Background.Visible = true
	else
		script.Parent.Parent.Background.Visible = false
		
	end
end)
