Twitter Redeem Code How-To, left script I made?

An simple fix is you add a Button called Submit or Enter so that every time it is clicked, it checks the text and if the text is correct then it gives the player whatever the code gives, for example;

This is the positions;

--------------StarterGui -----------ScreenGui ---------TextBox ---------SubmitButton(TextButton) -------LocalScript

This means StarterGui is the main parent, then screen Gui and inside of ScreenGui you have a TextBox and a button and inside of button you have the local script which is the controller,

Now code;

local Plr = game.Players.LocalPlayer
local shop = script.Parent.Parent.Parent:WaitForChild('ShopGUI').ShopMaster -- This line may have to be changed
local SB = script.Parent -- SubmitButton
local CB = SB.Parent:WaitForChild('TextBox') -- change the name to whatever you named your textbox
local Code = 'Code1' -- change this to your code
local CodeKnife = game.ReplicatedStorage.Knives:WaitForChild('CodeKnife')

SB.MouseButton1Down:Connect(function() -- functions on click
	if CB.Text == Code then
		CodeKnife:Clone()
		CodeKnife.Parent = Plr.Backpack
	end
end)

Make sure you have all Gui Objects and change what is necessary. If you followed along and did everything then it should work, if it doesn't work comment the error or fix it if you can.

:WaitForChild() waits for the child to load in so that it would work in both studio and game.

If this helped then please accept answer ;)

Good luck and have fun developing!
