Perhaps I'm missing something, but I can't see any way to have a conditional 'next' button.
For example, if I make a 'Hangman' or 'Memory Game' page type, I'd like to only allow students to advance on to the next page when they have completed the game, but they are able to skip it without even attempting. (As far as I know, I am using the most up-to-date version of Xerte, on a JISC sandpit.)
No it's not possible do that at this point. Disconect the next button is only possible when you use the connector pages and there is no connector page with the game hang man....
