A player name to display of who sent the nuke, a script error is displayed instead. Any solutions?

local local_plr = game:GetService("Players").LocalPlayer
game.ReplicatedStorage.GUI.OnClientEvent:Connect(function()
	script.Parent.TextTransparency = 0
	script.Parent.Text = local_plr
	wait(0.1)
	script.Parent.Text = (local_plr .. "H")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HA")
	wait(0.1)
	
	script.Parent.Text = (local_plr .. "HAS")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS S")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SE")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SEN")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT O")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT OU")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT OUT")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT OUT A")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT OUT A N")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT OUT A NU")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT OUT A NUK")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT OUT A NUKE")
	wait(0.1)
	script.Parent.Text = (local_plr .. "HAS SENT OUT A NUKE!")
		
		wait(3)
		script.Parent.Text = ""
		
	
end)

script error is here: Players.xp5u.PlayerGui.Announcement.Nuke alert.LocalScript:4: invalid argument #3 (string expected, got Instance) - Client - LocalScript:4

It is a localscript in startergui
