Recording Completion in Storyline 3

Hi, everyone. I have completed an updated version of our safety training from last year. I have published it as SCORM 1.2-compliant and asked for completed/not completed. I have tried two approaches. One is a button with an "Exit Course" trigger, the other is an instruction to click the EXIT button that appears on every Storyline 3 slide. In both cases, testing the course, the LMS did not record completion. I'm at a loss. I cannot use Storyline 360 (or get my hands on a completion trigger from 360). I would be grateful for any pointers about how to get the course to register completion. Success Factors is the LMS it's mounted on. Thank you!
