lmsAPI Functionality in HTML5 Output

I've been following several threads on this topic after trying to get a student's first name to appear in a Storyline 360 course with Cornerstone LMS. I'm publishing in HTML Only using SCORM 2004.

The code I've culled from various threads that almost works is:

var player = GetPlayer();

function findLMSAPI(win) {
// look in this window
if (win.hasOwnProperty("GetStudentID")) return win;

// all done if no parent
else if (win.parent == win) return null;

// climb up to parent window & look there
else return findLMSAPI(win.parent);
}

var lmsAPI = findLMSAPI(this);
var myName = lmsAPI.GetStudentName();
var array = myName.split(',');
var newName = array[1] + ' ' + array[0];
player.SetVar("newName", newName);

When I insert the variable onto a page, "undefined" is right before the user's name (first and last).

I've tried code almost identical to the above to get just the first name, but it yields nothing in the variable.

var player = GetPlayer();

function findLMSAPI(win) {
// look in this window
if (win.hasOwnProperty("GetStudentID")) return win;

// all done if no parent
else if (win.parent == win) return null;

// climb up to parent window & look there
else return findLMSAPI(win.parent);
}

var lmsAPI = findLMSAPI(this);
var name = lmsAPI.GetStudentName();
var nameArray = name.split(", ");
var firstName = nameArray[1];
var lastName = nameArray[0];
var player = GetPlayer();
player.SetVar('first_name',firstName);
player.SetVar('last_name',lastName);

Anyone have any ideas why this woulnd't be working?
