Registration Form for Limited Spaces

You have so many great forms, but I am unable to locate one that lets me set the number of registrations we can accept, then that number decrements as people sign up.  For example, we have 14 spaces available. When two people sign up, that availability number should decrease to 12. 

Do you have such a form?

2. If you want to show the remaining submissions, add the submissions counter widget to your form then set it to remaining submissions.
