Custom drag and drop - skipping to next slide without a trigger
I have created a couple of custom drag and drop interactions, that I'm not using as part of quiz; but purely ways of displaying content and testing knowledge (no results slides)
On the first slide, I have created my own submit button, which has a number of triggers attached to it - these depend if the learner correctly answered the five drag/drop items correctly.
Here's the problem - when I preview the slide on its own, the slide performs exactly as it should. When I preview the entire project however, the Submit button is pushing to the next slide (this is NOT one of the triggers assigned to it by the way)
When I look at the Story view, I can see two paths to the next slide - there should only be one. When I hover over them, the one I designed shows up, but the other one doesn't show any detail. (See image attached)
So I'm really stuck here. I don't want to use the submit button on the player, so this option is ruled out. I also want to avoid creating another submit button, as there are so many triggers attached to it.
Has anyone else experienced this? I've attached a copy of the story file as well. Hoping the community can help.
