Pulling first name from LMS

I have revised the code a little with a few improvements.  ...and, I can confirm this code works with Saba LMS and Moodle.  The attached file is for Storyline 360, but the code itself should work with Storyline 2 files.  Published setting format: HTML5 with Flash fallback and also works with HTML5 only setting!

Be sure to create a variable named username in Storyline.

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 full_name = array[1] + ' ' + array[0];
var first_name = array[1];

// Remove blank space from the front of variable
full_name = full_name.trim();
first_name = first_name.trim();

// Remove blank space from the end of variable
full_name = full_name.replace(/\s+$/, '');
first_name = first_name.replace(/\s+$/, '');

// If value exists change variable, if not change name to participant
if (first_name) {
player.SetVar("username", first_name);
}else{
player.SetVar("username", "Participant");
}
