Attempts statistics are not able to be generated for those surveys with one or more fill in multiple blanks questions. If the survey does not contain any questions of this type, the statistics for the attempts are able to be generated without an error.
Scope: All surveys that have at least one Fill in Multiple Blanks question.
Status: Blackboard has identified this as a bug and has slated to fix this in 9.1 Service Pack 16.
Reported for: 9.1 Service Pack 12.
References: BB-570.Work around: If creating a survey, do not utilize fill in multiple blanks questions. If you already have a survey, remove all fill in multiple blanks questions.
