Why wont this player has entered gui work?

game.Players.PlayerAdded:connect(function(plr)
		game.StarterGui.GreenieEntered.Frame.Visible = true
		game.StarterGui.GreenieEntered.Frame.TextLabel.Text = "A Greenie".."("..plr.Name..")".."has joined The Glade!"
		wait(30)
		if game.StarterGui.GreenieEntered.Frame.Visible == true then
			game.StarterGui.GreenieEntered.Frame.Visible = false
		end
	end)

-- for some strange reason it doesn't work! please help...

Your script appears just fine, apart from the fact that you are editing StarterGui! That means it won't show up to anyone unless they respawn. To edit GUIs in real time, you should edit PlayerGui.

game.PlayerGui.GreenieEntered.Frame.Visible = true
