Thanks Vlad,

Yes sorry I should have been more specific, it is scorm activities. When I click on the track details I only get cmi.core.lesson_location, cmi.core.lesson_status, cmi.core.total_time and cmi.suspend_data with a bunch of numbers.

Is that just a limitation of what's been sent to the LMS - what do the numbers under the suspend data mean?
