Storyline: Marking course status as "failed" in SCORM Cloud via JS

All,

We have a need to set the status of a course to either complete or failed, and, due to some unique assessment requirements, we need to do it through a Javascript trigger.  I have successfully been able to have the course status marked as "Complete" in SCORM Cloud using the following Javascript in the trigger:

SetStatus("completed");

When I try to set it to failed using the following Javascript through the SCORM Cloud completion status still stays as "Incomplete" (and success as "Unknown").

SetStatus("failed");

I was under the impression that you could pass any of the following into that command to change the LMS value: completed; failed; passed; incomplete.

Can anyone please provide me any guidance as to how I can tell SCORM Cloud to mark the course as "failed" specifically...we're under a major time crunch.

Thank you!

Sean
