scorm - How to do you call to LMS from Captivate 8 -

how send user variables / data lms captivate 8?

have tried following no luck:

to send data:

document.getelementbyid('captivate').scorm_calllmssetvalue("cmi.core.lesson_status", "passed"); 

to retrieve data:

var str = document.getelementbyid('captivate').scorm_calllmsgetvalue("cmi.core.lesson_status"); 

display retrieved data in captivate:

window.cpapiinterface.setvariablevalue("lessonstatus", str ); 

captivate shows result as: 0

any appriacated!

i believe captivate 8 uses scorm driver it's scorm tracking. here's documentation scorm driver.
