JavaScript Help - Adding 5 variables to 1 for a Total Score in Storyline

Does anyone know why my JavaScript trigger isn't working in Storyline? I have 5 scenarios, each with a sectional score (ScorePessimist, ScoreExpert, etc.). I also want to show a Total Score (ScoreTotal) as learners can self-select the order in which they tackle the scenarios from a Menu. The Total Score should be the sum of all of the sectional scores.

 

Attempt 1) This worked and updated the ScoreTotal variable in Storyline to 10.

var player = GetPlayer();

var ScoreTotal1 = 10;

player.SetVar("ScoreTotal", ScoreTotal1);

 

Attempt 2) This did nothing, Total Score stayed at 0.

var player = GetPlayer();

var ScorePessimist1 = player.getVar("ScorePessimist");
var ScoreExpert1 = player.getVar("ScoreExpert");
var ScoreIndecisive = player.getVar("ScoreIndecisive");
var ScoreImpatient = player.getVar("ScoreImpatient");
var ScoreAggressor = player.getVar("ScoreAggressor");


var ScoreTotal = ScorePessimist + ScoreExpert + ScoreIndecisive + ScoreImpatient + ScoreAggressor;

player.SetVar("ScoreTotal", ScoreTotal);

 

Attempt 3) This did nothing, Total Score stayed at 0.

var player = GetPlayer();

var ScoreTotal1 = player.getVar("ScorePessimist") + player.getVar("ScoreExpert") + player.getVar("ScoreIndecisive") + player.getVar("ScoreImpatient") + player.getVar("ScoreAggressor");

player.SetVar("ScoreTotal", ScoreTotal1);

 

Each of my sectional scores (for example, ScorePessimist) are number variables adjusted by 10 or -10 each slide.

 

I'm not very familiar with JavaScript so any help would be appreciated!

 

Best,

Sam

    You don't need JavaScript to add the value of variables. Just use a set of triggers like these: 

    • The first trigger, which sets the ScoreTotal to 0, is used to ensure that the scores don't get added more than once (for example, if the user revisits the slide). 
    • Instead of "when the timeline starts," the triggers could be attached to a button. 
    • In the Trigger Wizard, any item with a dashed underline can be edited. That's how to access the math operators:

    And if for some reason you need ( or want ) to use Javascript... the trick needed is converting the received variable to a numeric...as Storyline variables always will be strings when grabbed by Javascript.

    So use parseInt( ) on a grabbed variable for calculation...

    eg:

    var scoreP = player.getVar("ScorePessimist");
    var scoreE = player.getVar("ScoreExpert");
    var scoreI = player.getVar("ScoreIndecisive");
    var scoreIm = player.getVar("ScoreImpatient");
    var scoreA = player.getVar("ScoreAggressor");

    var ScoreTotal1 = parseInt(scoreP)+parseInt(scoreE)+parseInt(scoreI)+parseInt(scoreIm)+parseInt(scoreA);

    player.SetVar("ScoreTotal", ScoreTotal1);
