Why is this code that reads a textbox not working properly?

local players = game.Players
local rblxCode

game:WaitForChild("Players").PlayerAdded:Connect(function(plr)
    rblxCode = plr.PlayerGui["rblx.basic"].Frame.TextBox.ContentText
    if rblxCode == 'Print("Hello, world!")' then
        print("Hello, world!")
    end
end)

How come this code would not work? When I join the game, it outputs the error: rblx.basic is not a valid member of PlayerGui "Players.pevdn.PlayerGui" Even though it definitely is. https://ibb.co/zFzc9YJ

You're trying to index the ScreenGui when the player joins, and it probably doesn't exist at that point.

You should use :WaitForChild() to make sure it definitely exists first. For example:

local gui = plr.PlayerGui:WaitForChild('rblx.basic')
