Hi Clive

When I go into a SCORM completion condition there is only an option for require status as Passed or Completed. There isn't a failed status but this is the status that is being checked in the Access restriction setting.

Can you go to the grade book record of a user who has completed the SCORM and see what the status is showing - it will be either Passed or Completed. Whatever value is here is the one you should select for the completion condition.

Then go into the second activity and select 'Restrict access' Learner Must not have the first activity marked as complete.

Regards
