Blackboard Not Recording Completion Status

I'm trying to get Blackboard to record the completion status, from the variable AICC_Score, which I set to 100 at the end of the module.  I'm using SCORM 1.2 to create the packages, and have set the modules to use HTML5 only.  We're sending the modules to someone else to put on their Blackboard system, so unfortunately, I don't know anything about how their system is set up, but I can certainly ask if I know the right questions.  (We get these same modules to work fine on Moodle).
