We have a course published as SCORM 2004, 4th edition. Several of the questions are FreeForm type.
The learners have to answer these questions before moving to the next slide. They cannot change their answer if they use the Prev button to go back.
We are noticing about 34% of the learners have a response listed as “undefined.” We cannot understand how they cannot answer the question, when they cannot move forward until they answer and if they return to the question they cannot change it.
