    Something appears to be broken. Anyone not getting a score when you press submit?

    Maybe I'm the one to blame. If so, then I discovered a bug. I think I had been first who entered the quiz, ran shortly over it, and then wanted to know the results without doing the quiz and hit "submit" on an empty list. As a result, the first question had vanished, so I had to refresh to get it back.

    Now I wanted to test it. And each time I hit "submit", this time with a filled out formula, again the first question on the lists vanishes. I stopped the procedure after I "killed" the first 4 questions. So my suspicion is, that something with the submit button is wrong. The underlying code seems to delete the first list entry instead of an evaluation. Perhaps a fix is to remove it and set it again, if that is possible.

    Sorry, uhm no sorry for that: I'm too curious. I continued and "killed" the rest of the questions untile there was an empty sheet. Then I hit "submit" again, and ever since the page has gone in state "loading" – which it can't since all list entries have gone. Funny bug.
