How do I make a GUI that when you hit a brick it appears, but after 60 seconds, it disappears?

I've tried for atleast 20 minutes now and I'm stuck.

Workspace.BG.Lolol.Touched:connect(function(hit)
    script.Parent.Visible = true
    wait(60)
        script.Parent.Visible = false
end)

Workspace.BG.Lolol.Touched:connect(function(hit)
    script.Parent.Visible = true
    wait(60)
        script.Parent.Visible = false
end)

Your current script has many problems, and, we need more information.

Assuming from what you have as of now, you have either a BillboardGUI or SurfaceGUI.

To start off, I suggest using a capital c because a lower case is deprecated

Workspace.BG.Lolol.Touched:Connect(function(hit)
    script.Parent.Visible = true
    wait(60)
        script.Parent.Visible = false
end)

now, we don't know what script this is, so, let's say "add a local script" (Local scripts work best when dealing with GUI)

There is no point of having "hit" since your not going to use it. Now I can help improve your code, but can not help you solve your problem. This is because information was lacking.

You can add a debounce so spam doesn't happen:

local a = true

Workspace.BG.Lolol.Touched:Connect(function(hit) -- hit is not needed, if this is a local script then do local plr = game.Players.LocalPlayer
	if a then
		a = false
		script.Parent.Visible = true
		wait(60)
 		script.Parent.Visible = false
		a = true -- so now it will become visible again
	end
end)

I can only help you to what I know and what should be done. I wish you luck on your goal.

You need to put a capital C in Connect. so it will be like this

Workspace.BG.Lolol.Touched:Connect(function(hit)

And ps: Just reminding you, if you want to affect one player only then put it in a local script.
