Voting starts in March for the Drupal Association Board election.
I want to create a report that shows the questions that are most frequently answered incorrectly.
I tried adding the field
Quiz Results by Question: Is Correct but it generates an error.
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'quiz_node_results.result_id' in 'on clause'
Any one have any idea how I would get these statistics?
