Choose Many Freeform Quiz Question won't work for me
I have a freeform Choose Many quiz question with a graphic of a check in the background. There are transparent boxes around the parts required for the check to be negotiable. When the user clicks a box the outline color changes. All boxes appear in form view and some are them are checked as correct answers. When I preview the slide, click on the boxes and hit Submit I get a popup "Invalid Answer; You must complete the question before submitting. I just can't find what I'm doing wrong. Can anyone help?
