How to access xAPI/Tin Can LMS variables in JavaScript

When Storyline 360 publishes a SCORM 1.2 or 2004 package, an entire library of SCORM JavaScript functions are created and can be used inside Storyline (for instance: SCORM_CallLMSGetValue("cmi.core....

This ended up working for me (this is the "passed" version... I also have a failed version):

var player = GetPlayer();
var iascore = { raw: player.GetVar("FinalPercent"),min:0,max:100 };
var iatc = new TinCan({url: window.location.href});
var stmt = { verb: "passed", inProgress: false, result: { } };
stmt.result.success = true;
stmt.result.score = iascore;
iatc.sendStatement(stmt);

I used a custom variable in Storyline called "FinalPercent" to obtain the Results.ScorePercent and report it back to the LMS.

    I am trying to achieve something similar in xAPI. In SCORM I would use the following code to pass score, success status and complete.

    var player = GetPlayer();
    var passPercent = player.GetVar("passPercent");
    var percentScore = player.GetVar("percentScore");
    function findLMSAPI(win) {
    if (win.hasOwnProperty("GetStudentID")) return win;
    else if (win.parent == win) return null;
    else return findLMSAPI(win.parent);
    }
    var lmsAPI = findLMSAPI(this);
    lmsAPI.SetScore(percentScore, 100, 0);
    if (percentScore >= passPercent){
    SCORM2004_CallSetValue("cmi.success_status", "passed");
    }else{
    SCORM2004_CallSetValue("cmi.success_status", "failed");
    }
    lmsAPI.SetReachedEnd();


    With xAPI I am attempting to use the following code based on above :

    var player = GetPlayer();
    var passPercent = {raw: player.GetVar("passPercent")};
    var percentScore = {raw: player.GetVar("percentScore")};
     var iascore = { raw: player.GetVar("percentScore"),min:0,max:100};
    var iatc = new TinCan({url: window.location.href});
    var passStmt = { verb: "passed", inProgress: false, result:{ } };
    var failStmt = { verb: "failed", inProgress: false, result:{ } };
    if (percentScore >= passPercent){
    passStmt.result.success = true;
    passStmt.result.score = iascore;
    iatc.sendStatement(passStmt);
     
    }else{
    failStmt.result.success= false;
    failStmt.result.score = iascore;
    iatc.sendStatement(failStmt);
     
    }

     

    Any idea where I am making a mistake? I would greatly appreciate any insights.
