How do I make it so it displays each letter of my name as if typed out?

I've made a GUI that welcomes you into the game when you join. It has a keyboard "animation" and types out the letters of your name, saying "Welcome, NAME!"

I've done the Welcome part which was easy, but I'm stuck on the name. I think it's something to do with a table but not quite sure. So we're on the same page here, I am making it so it is like this:

W We Wel Welc Welco Welcom Welcome

Anyways, here's my current code!

--Variables
local plr = game.Players.LocalPlayer
local welcomeMessage = script.Parent.welcomeMessage


script.Parent.ResetOnSpawn = false


--Functions
function welcome()
	wait(1)
	welcomeMessage.Text = "W"
	wait(0.07)
	welcomeMessage.Text = "We"
	wait(0.07)
	welcomeMessage.Text = "Wel"
	wait(0.07)
	welcomeMessage.Text = "Welc"
	wait(0.07)
	welcomeMessage.Text = "Welco"
	wait(0.07)
	welcomeMessage.Text = "Welcom"
	wait(0.07)
	welcomeMessage.Text = "Welcome"
	wait(0.07)
	welcomeMessage.Text = "Welcome,"
	wait(0.07)
	welcomeMessage.Text = "Welcome, "
	wait(0.07)
	welcomeMessage.Text = "Welcome, " .. plr.Name[3]
end

if welcomeMessage.Visible == true then
	welcome()
end

Hello! removing the "[3]" from the line where you add the player name fixes the issues. But maybe there's a reason I'm not seeing for it being there? Also I recommend actually animating the text instead of using waits and manually setting the text.

Here's the link to that:

Hope this helps!
