How can I get my text button invisible for 7 seconds right after someone joins my game?

How can I get my text button to be invisible for 7 seconds of someone joining my game, then become visible again after the seven seconds?

this isn't working, any mistakes or errors?

game.StarterGui.PicWithButton.TextButton.Visible = false wait(7) game.StarterGui.PicWithButton.TextButton.Visible = true

1. Visible isn't a property, try transparency.

game.StarterGui.PicWithButton.TextButton.Transparency = 1 -- Makes it invisible 
 wait(7) -- Waits seven seconds until it fires again 
game.StarterGui.PicWithButton.TextButton.Transparency = 0 -- Makes it visible 

If you want this to happen when a player enters you should do,

game.Players.PlayerAdded:connect(function()
	game.StarterGui.PicWithButton.TextButton.Transparency = 1 -- Makes it invisible 
	 wait(7) -- Waits seven seconds until it fires again 
	game.StarterGui.PicWithButton.TextButton.Transparency = 0 -- Makes it visible 
end)

I suggest, you should explore all the properties of a GUI before using them.

When you edit the StarterGui, it doesn't change the PlayerGui.

Assuming you're using a LocalScript,

repeat wait() until game.Players.LocalPlayer.Character
game.Players.LocalPlayer.PlayerGui.PicWithButton.TextButton.Visible = false
wait(7)
game.Players.LocalPlayer.PlayerGui.PicWithButton.TextButton.Visible = true

Hope I helped!
