RSA quiz problems answered for GCIT my.TAFE students

This video shows what students need to do to ensure that they can complete the RSA quiz properly within my.tafe. The next button doesn't work until you've moved enough of the answer boxes to the question area. Notice that initially the next button is there but greyed out and doesn't work in the first and there is no done button, which is what allows you to move on. When I've only partly answered the question, there is still no done or working next button. When I have moved all the tiles across the done button appears. When I click that the answer is checked and the next button becomes active.
