Here’s a screenshot of my D&D activity. If someone does not put these icons into the correct category, they will get a feedback message upon clicking the submit button. This says for them to try again. If they are not correct in their choices, I need all of the icons to go back to their original locations.
@nstephenson4471 can you put that page into a Library Object and attach it here? I would like to see why Change Contents would not reset that question (for change contents select the question and just leave the value empty).
@schapman1885 Sorry I’m not understanding the question. Executing a Change Contents with the Question object as the target and no value (blank, empty) would reset the question back to unanswered, and move back the drag items. Are you using a Drag / Drop question or is this some other custom interaction?
