I need help with this task. I would like to create an app/webpart in SharePoint 2013 Foundation that displays a list of events. Users can see this and if interested can signup for which ever event by clicking or filling out a form. Once the action is completed from the user, they are automatic added to the event. There will be a "status" column stating OPEN or CLOSED. Once CLOSED it will no longer be display or will not accept new registrations.
I have tried this with two custom lists but the issue is the chance for users to cause errors (the user might not type their last name). Also there is no way to automaticly increase the number of attendees by one once the user completes the registration. I have also tried getting the data of the user ID, checking how many IDs are listed, display the number and calculate if its < or = to the total number stated (to determine if the event is OPEN or CLOSED) but calculated column will display the only the first ID number.
I also tried creating a survey, taking the responses from the survey and updating a custom list but it wasn't working either.
I can't figure out how to approach this or maybe should see a different way of approaching this.
I attached an image of what I'm trying to say visually.
