Text box only gives message when it has no Text?

Question

So I'm making this game and the user has to enter a custom name, but whenever I test it and put a name, it always comes up with the response used when there is nothing there.


--things--
local WR = script.Parent.Parent:WaitForChild("Warning")
local NM = script.Parent.Parent
local NN = game.ReplicatedStorage:WaitForChild("NewName")
--texts--
local preview = "My name is"..NN.Value
local warning2 = "This field cannot be blank."
--variables--
--script--
script.Parent.MouseButton1Click:Connect(function()
	if NM.Text ~= "" then
		script.Parent.Visible = false
		repeat wait()
			NN.Value = NM.Text
		until NN.Value == NM.Text
		for a = 1,#preview do
			WR.Text = string.sub(preview,1,a)
			wait()
		end
		wait(3)
		WR.Text = ""
	else
		script.Parent.Visible = false
		for a = 1,#warning2 do
			WR.Text = string.sub(warning2,1,a)
			wait()
		end
		wait(3.2)
		script.Parent.Visible = true
	end
end)
