Getting student name from the LMS and using it in Articulate

Publishing Using HTML5 on Cornerstone LMS, This code was sort of working but giving me a duplicated name...
By modifying it slightly I was able to get rid of the duplication and have the full name display.

I was hoping to separate the first and last name, but (after 22 attempts) I've decide to settle with it working this way.

The on-slide reference display variable is: %newName%

and the JS code was as follows:

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[0];
player.SetVar("newName", newName);

Thanks for the starting point!
