I have a workbook that is almost complete. This will be called an NFL Knockout pool. Each week users will pick a team to win on the “Picks” Sheet, or a way you may seem appropriate. Once they pick that team, they cannot choose that team again. Users will register with their Name, email, and phone number. They will also create a username and password. I have created userforms for both. Once the register I want them to only have access to the “Picks” Sheet where they will make their picks each week. I will have several Admin users that will have access to all sheets. I have created dynamic drop-down menus for each row in the “Picks sheet” so that once a team is picked it will drop off the list. This is not for public access so this is just for fun and real money will not be involved. No personal information is to be leaked. Thanks.
