Storyline not generating reports for survey in html5
I've been putting together a survey for my department and am having some difficulties obtaining results when the survey is completed on a mobile device (html5). When a user views the survey on their mobile device, articulate online does not tabulate their answers under answer breakdown/ attempt detail. However, it still shows that the user has attempted the survey, but regards it as being "incomplete". I've even added a graded multiple-choice question and a results slide but that still hasn't solved the question.
Attached is the storyline file in question. If anyone could take a look at it and provide a solution that would be most appreciated.
