LocalPlayer names aren't displaying?

Hello there, I'm quite new to this field. I was thinking of creating a register with a Surface GUI. My attempt is to display the the local player's username when the "login" button is clicked. This is how I completed;

script.Parent.Frame1.Username.Text = ("Username:" .. game.Players.LocalPlayer.Name)
script.Parent.Frame2.LoginButton.MouseButton1Click:connect(function()
	print(game.Players.LocalPlayer.Name)
	end)

Username = The text label for Frame1. My expected output.

LoginButton = A text button for login.

Sadly, my expected output isn't printed in Frame1,

Is there something wrong with the concatenation and string?

Thank you.

Why do you have Text = ("")?

script.Parent.Frame1.Username.Text = "Username: " .. game.Players.LocalPlayer.Name

script.Parent.Frame2.LoginButton.MouseButton1Click:Connect(function()
	print(game.Players.LocalPlayer.Name)
end)
