Users can't submit form

Hi everybody,

we recently hostet an internal pubquiz for our employes in which they entered there questions via typeform in realtime and we used the calculator to add up their points. In theory, this worked out great, but over 4 rounds, 5-10 of our 40 teams had difficulties submitting their responses. The error message said something like “unable to submit form”.

Do you have any idea what we can change to avoid this next time? This caused a lot of frustration and delay in the live situation.

Two possible reasons might be:

1. I entered the team names as a single choice question right before users opened the form. Might a last minute change in the form cause problems?
2. Users skipped back and forth between questions. Can this confuse the calculator?

Thank you very much for your help!
