How do you make a Gui that appears whenever someone joins the game?

Hey, guys! I was trying to make a player entered Gui that appears and slides down the screen whenever someone joins the game. This is what I tried:

game.Players.PlayerAdded:connect(function(player)
	local msg = Instance.new('ScreenGui', game.StarterGui)
	local frame = Instance.new('TextLabel', msg)
	frame.BorderSizePixel = 2
	frame.BoderColor3 = Color3.new(0,0,0)
	frame.Position = UDim2.new(0,560,0,-30)
	frame.Size = UDim2.new(0,200,0,30)
	frame.Text = player.Name .. " has joined the game."
	for i = 1,50 do
		frame.Position = frame.Position + UDim2.new(0,0,0,1)
		wait(0.01)
	end
	wait(3)
	for i = 1,50 do
		frame.Position = frame.Position - UDim2.new(0,0,0,1)
		wait(0.01)
	end
	msg:Destroy()
end)

This is inside a regular script, inside the Workspace. If anyone can help me and explain what I did wrong, I would gladly appreciate it!

You are really close. You just need to put the message in the PlayerGui of the Player, not the StarterGui.

  local msg = Instance.new('ScreenGui', player.PlayerGui) -- This is to replace line 2
