Create a challenge.
Set sign ups to "Number of requests per sign up" to require 0, up to 3 and to require Warnings
Attempt to sign up
Requests is fully collapsed. Select "Add Another Request?" (why is that a question?)
Note the number of the request:
Add a second request. second request is also NaN
Select a warning in the "second" request.
screen scrolls to "first" request, update first request, not second.
Submit the Signup
Signup page is blank
Select Edit Signup
Signups, such as they were, are missing.
As an aside, it will happily "accept" four signups in this paradigm, because they're all the same signup.
What should happen:
Requests/offers should be minimum 1
