The problem lies in the fact that you're trying to calculate your score variable when the slider question page is displayed (you're adding stuff in the addOnLoad function).
I suggest the following implementation: after the slider question create a page for calculating the score variable like this:
!
And add the following JavaScript to the Calculating Score Q:
var s1scr = parseInt("${q://QID3/ChoiceNumericEntryValue/1}");
var score = 0;
if (s1scr >= 50) {
score = 30;
}
Qualtrics.SurveyEngine.setEmbeddedData("score", score);
this.clickNextButton()
Note: I changed the if to >= as it is easier to test and used clickNextButton() as opposed to a timer with Auto-Advance time - in my experience, a timer with Auto-Advance set to a minimal time throws the JS off so this is a solid way to ensure JS execution.
Hope that helps!
@npetrov937 thanks for your prompt reply, it was very helpful.
Another question that popped up concerning the current experiment.
I want to repeat the same block 10 times. After each time I want to show the result of the current round. At the end (after 10 rounds) I want to show the aggregated score of all rounds.

Hi
@Eski ,
I would suggest taking the same process described above and replicating it as many times as you need. In your case, create 10 slider questions. Then in the javascript code pull all of the values from the sliders and save them to different score variables (if you need to save them); then aggregate them - it would look something like this:
var slider1 = parseInt("${q://QID3/ChoiceNumericEntryValue/1}"); //replace with your own sliders //id's
var slider2 = parseInt("${q://QID3/ChoiceNumericEntryValue/1}");
var slider3 = parseInt("${q://QID3/ChoiceNumericEntryValue/1}");
var score1 = 0;
var score2 = 0;
var score3 = 0;
var avgScore =0;
if (slider1 >= 50) {
score1 = 30;
}
if (slider2 >= 50) {
score2 = 30;
}
if (slider3 >= 50) {
score3 = 30;
}
avgScore = (score1+score2+score3)/3 //calculating the mean score
//setting the already-created embedded data variables score1, score2, score3, avgScore
Qualtrics.SurveyEngine.setEmbeddedData("score1", score1);
Qualtrics.SurveyEngine.setEmbeddedData("score2", score2);
Qualtrics.SurveyEngine.setEmbeddedData("score3", score3);
Qualtrics.SurveyEngine.setEmbeddedData("avgScore", avgScore);
this.clickNextButton()
Copy-paste as much as you want. Obviously, the code can be written in a much better way but at least this way it is quite clear.
Hope that helps.
Thanks for your reply!
I've built my experiment based on your guidelines, however after calculating the aggregated variable (within the JavaScript) I'm not able to set the value back to the embedded field I've created within the Survey Flow and it keeps giving me the initial value of 0. What can be the reason?
Attached the code and screens from my experiment:

TR1MIS isn't a valid question id. I suspect that is the question label. A question id is in the form QIDx, where x is number.
Thanks
@TomG I've figured it out before you've answered.
Btw, there's a more elegant way to right the code?

Definitely. How about:
```
var trn1Vals = [
parseInt("${q://QIDx/ChoiceNumericEntryValue/1}"),
parseInt("${q://QIDx/ChoiceNumericEntryValue/2}"),
...
parseInt("${q://QIDx/ChoiceNumericEntryValue/36}")
];
var trn1Score = 0;
jQuery.each(trn1Vals, function(i, val) { if(val == 50) trn1Score = trn1Score + 30; });
Qualtrics.SurveyEngine.setEmbeddedData("trn1Score", trn1Score);
this.clickNextButton();
```
Thanks
@TomG but unfortunately, when I'm trying to put this code it doesn't advance to the next page, and when manually clicking on next page it doesn't show the calculated value at all.
You replaced the ... with the rest of the piped values and QIDx with the actual QID number, correct? Check the console for errors.
Does
${q://QI#/ChoiceNumericEntryValue/1}
give the value of the selection on a slider on the most recent version of qualtrics? I can't even console.log this.
And yes, I have the proper ID, quotes, and it is executed on "unLoad."
