Save quiz data

Hello,

I'm a beginner on storyline and I want to save the quiz result in my database. I don't use any lms or external plateform.

When I'm on the result slide,  I just want to get the quiz result in javascript. I've created a trigger on that slide which execute javascript code :

var player=GetPlayer();
alert("Your score is, " + player.GetVar(Results.ScorePoints));

Results.ScorePoints is null...

I want all details about the questions / answers, the score the quiz status... in javascript.

Could you help me ?
