Actually, whichever options I tick for the Exit Page, I don't get a link to the next activity. I have tried various combinations of Encouragement/retry/your grade for that attempt. But I don't get a link. Please see screenshot below. However, as my students are non-readers, a choice of different links wouldn't help anyway.
You say that if the last task is completed successfully TaskChain continues to the next activity. But as my chains are very long I like to break them up with encouragement. So the last "task" is just an HTML page with information. Maybe that's why I can't get it to carry on to the next activity?
In Quizport the Continue button that appeared at the bottom of the End of Unit page would lead to the next Activity if this was set. But in TaskChain that button just leads back to the same page. If I could get this button to lead to the next activity it would solve my problem.
Sorry to be so complicated.
