Dear Qualtrics community,
I have a survey where I ask people to guess the percentage of women in different sector.s I want to assign to them one point for each of the correct answer.
i.e. "What is the percentage of women in Economics?" and then they have to slide a slider from 0 to 100. If they guess the correct answer, (which in this case let's say it's 48 percent) then they get one point.
Then I repeat the questions for different sectors and I calculate the total score of correct answers.
I tried to implement this code but with no success.
Qualtrics.SurveyEngine.addOnPageSubmit(function(){

let solution = 48

let sliderValue = Number(document.getElementById('QR~'+this.questionId).value);

let score1;

console.log(sliderValue)

if(solution === sliderValue){

score1 = 1

}else{

score1 = 0

}

let text1 = Qualtrics.SurveyEngine.setEmbeddedData("score1", score1)

let totalScore = Number(score1) 



});
I also attach here the .qsf of the survey! Thank you very much in advance!

For who is interested, I managed to solve the problem by putting after my slider questions an empty question with this Javascript code:
I also created the correspondent embedded field in Survey Flow (i.e. score2_2 etc.)
I basically stored the value of each slider in a variable and then sum all of the variables to create the total score. Hope this helps!

var slider2_1 = parseInt("${q://QID48/ChoiceNumericEntryValue/1}"); 
var slider2_2 = parseInt("${q://QID48/ChoiceNumericEntryValue/2}");
var slider2_3 = parseInt("${q://QID48/ChoiceNumericEntryValue/3}");
var slider2_4 = parseInt("${q://QID48/ChoiceNumericEntryValue/4}");
var slider2_5 = parseInt("${q://QID48/ChoiceNumericEntryValue/5}");
var slider2_6 = parseInt("${q://QID48/ChoiceNumericEntryValue/6}");

var score2_1 = 0;
var score2_2 = 0;
var score2_3 = 0;
var score2_4 = 0;
var score2_5 = 0;
var score2_6 = 0;

  var totalScore2 =0;


   if (slider2_1 == -17) {
   score2_1 = 1;
   }
   if (slider2_2 == -13) {
   score2_2 = 1;
   }
   if (slider2_3 == -10) {
   score2_3 = 1;
   }
   if (slider2_4 == -8) {
   score2_4 = 1;
   }
   if (slider2_5 == -6) {
   score2_5 = 1;
   }
   if (slider2_6 == -10) {
   score2_6 = 1;
   }

  totalScore2 = (score2_1+score2_2+score2_3+score2_4+score2_5+score2_6) //calculating the mean score

//setting the already-created embedded data variables score1, score2, score3, avgScore
  Qualtrics.SurveyEngine.setEmbeddedData("score2_1", score2_1);
  Qualtrics.SurveyEngine.setEmbeddedData("score2_2", score2_2);
  Qualtrics.SurveyEngine.setEmbeddedData("score2_3", score2_3);
  Qualtrics.SurveyEngine.setEmbeddedData("score2_4", score2_4);
  Qualtrics.SurveyEngine.setEmbeddedData("score2_5", score2_5);
  Qualtrics.SurveyEngine.setEmbeddedData("score2_6", score2_6);
  Qualtrics.SurveyEngine.setEmbeddedData("totalScore2", totalScore);
