How to make a code GUI opener ?

script.Parent.MouseButton1Click:connect(function()
	if script.Parent.Parent.Input.Text == 'Code1' then
		script.Parent.Text = 'Success!'
		script.Parent.Parent.Input.Text = '112'
		wait(1)
		script.Parent.Text = 'Submit'
	elseif script.Parent.Parent.Input.Text == '112' then
		script.Parent.Text = 'Success!'
		script.Parent.Parent.Input.Text = '112'
		wait(1)
		script.Parent.Text = 'Submit'
	elseif script.Parent.Parent.Input.Text == 'Code3' then
		script.Parent.Text = 'Success!'
		script.Parent.Parent.Input.Text = '112'
		wait(1)
		script.Parent.Text = 'Submit'
	else script.Parent.Parent.Input.Text = '112'
		script.Parent.Text = 'Incorrect Code'
		wait(1)
		script.Parent.Text = 'Submit'
	end
end)
script.Parent.MouseButton1Click:connect(function()
	script.Parent.Parent.Frame.Visible = not script.Parent.Parent.Frame.Visible
end)

-- Follow DRY (Don't repeat anything) and index variables before you need them.
local button = script.Parent
local grandfather = script.Parent.Parent
local Input = grandfather:WaitForChild('Input')
local frame = grandfather:WaitForChild('Frame')


-- Use a dictionary array
local accepted_codes = {
	
	code1 = true;
	code3 = true;
	['112'] = true;
	
}

-- Use a debounce to prevent spamming it
local debounce = true
local function display(success)
	-- ternary operators are a short hand for if else statements
	button.Text = success and 'Success' or 'Incorrect Code'
	Input.Text = success and '112' or Input.Text
	wait(1)
	button.Text = 'Submit'
end

-- Use MouseButton1Down
button.MouseButton1Down:connect(function()
	if debounce then 
		debounce = false
		if accepted_codes[Input.Text:lower()] then 
			display(true)
		else
			display(false)
		end
		debounce = true
	end
end)

button.MouseButton1Click:connect(function()
    frame.Visible = not frame.Visible
end)
