How do I see what a player types in a textbox and see if its correct?

So i'm making this game were there is a pyramid and you have to put a code into a text box and if you get the code correct you may pass. The only problem i have is seeing what the player typed in the text box and see if its correct.Here is my script im looking for a better way

if script.Parent.Text == "2020" then
print("yeayy")	
end

script.Parent.Changed:Connect(function (text) -- this will trigger the function whenever the text is edited

	if text == "2020" then

		--Code goes gere

	end

end)

This is a better solution if you are finding out whether the player has stopped typing and unfocused the box.

script.Parent.FocusLost:Connect(function() -- When the focus is lost, fire this
	if script.Parent.Text == "text" -- If the input is correct
		-- Code here
	end
end)
