TextLabel is not changing?

My localscript is not changing the text, no errors in the output or anything I have no idea why so i just decided to ask here whats the problem? What i want to do here is change everybodies text with the typewrite effect

for i,v in pairs (game.Players:GetPlayers()) do
local TextLabel= v.PlayerGui.ScreenGui.TextLabel
	local function typewrite(object, text, length)
		for i = 1,#text,1 do
			object.Text = string.sub (text,1,i)
			workspace["UnderTale - Text Sound(Fixed)"]:Play()
			wait(length)
			TextLabel.Visible = true
		typewrite(TextLabel, "Text")
		wait(1)
		typewrite(TextLabel, "Text2")
		wait(1)
		typewrite(TextLabel, "Text3.")
			wait(3)
			TextLabel.Visible = false
			TextLabel.Text = "-"
		end
	end
end
