Custom xAPI Statement Doesn't Work

I am trying to capture step-by-step learner actions in my course.  I am publishing my Storyline 360 file to "Report to an LMS - xAPI (Tin Can API)."  Then, I am running it in SCORM Cloud to see what data it reports. 

I've been successful adding custom text with triggers to send xAPI statement.  However, when I try to send a variable following the instructions here, nothing shows up on the data stream: https://articulate.com/support/article/Storyline-360-How-to-Send-the-Value-of-a-Variable-to-an-LMS#custom-xapi-statements.  See the two attached images.  What am I doing wrong? 

Also, is there a way to send multiple variables in one custom xAPI statement with descriptive text identifying what each variable is?

Thanks for your help!
