Quiz not recording responses

Thanks for sharing your file. There is a lot going on here that is creating the issues.  When a question is created in Storyline, Storyline already builds in the needed triggers, layers, etc. for this to work.  Editing those can be creative, but can also break the functionality. . . which is the case here.

The Feedback Layers created are not recognized by Storyline as the correct and incorrect layers. The feedback generated by Articulate was deleted.

The Submit Interaction trigger was edited and then disabled and replaced by Show Layer Triggers. This will prevent the proper layers and scoring from working.

The custom radio buttons you created are covering up the choices you are measuring in the form. So when a choice looks like it is being made, it is not really being made. So no score was ever being calculated.

I have repaired the first question in the list to give you one idea of how you might choose to redesign this.  There are always other ways to do this.  But we always encourage users to let SL do the heavy lifting when working with quiz questions. It will do most of the work for you, then you can edit to your satisfaction as long as you do not break the mechanics it has built.
