I have a website using Joomla on which i host a soccer game. Users log each week and choose a team. If that team wins they continue playing, if it loses they're out. For example week1 they pick Chelsea, if Chelsea win they can play in week2. but in week2 they can pick any team EXCEPT Chelsea. And so on each week.
So i need something that lets users choose from a list of teams, then each subsequent list does not include teams chosen before. So week1 would have 20 choices, week2 19, week3 18,etc. I would like to be able to lock the choices at then end of each week so it still displays there choice for week1 but they can't change it in week2. Hopefully thats clear, just one page writing to MySQL
