Just listen to the instructions in the project itself
My sister had a diary with a lock. so i wanted to make an "algorithm" that will break the lock. It also checks if the written number format is correct etc. I dont want to beg but please heart and fav as i want the project to reach other people. I am trying to prove that scratch is not for games and animations only. I also made another project for logging in (Do check my profile please) Thank you all... Here is you cookie ?
