JavaScript code doesn't execute properly

1. Thanks for explaining that

2a) It's was already set to "none" the whole time
2b) I put the code into addOnLoad, but the problem still persists

I meant "Qualtrics.SurveyEngine.addOnReady" of course.

This is my code:

Qualtrics.SurveyEngine.addOnload(function()
{

});

Qualtrics.SurveyEngine.addOnReady(function()
{
//FUNCTIONS -############################

function add(a, b) {
return a + b;
}

function roundTo(n, digits) {
var negative = false;
if (digits === undefined) {
digits = 0;
}
if( n < 0) {
negative = true;
n = n * -1;
}
var multiplicator = Math.pow(10, digits);
n = parseFloat((n * multiplicator).toFixed(11));
n = (Math.round(n) / multiplicator).toFixed(2);
if( negative ) {
n = (n * -1).toFixed(2);
}
return n;
}

It's basically calculating averages in the survey horizontally.
Think participants can answer questions in areas A1, A2, A3 , B1, B2, B3, etc. and the code calculates the averages of A, B, C, D E and an overall average.

The tricky part is (also the reason why I chose to do it in JS) that A, B, C, D, E are optional, so participants pick 1 to 5 areas to answer and I need to account for that when calculating the averages. I have done that by using an array for areas A, B, C, D, E and divide by the array length, which accounts for the number of chosen areas.

I was using the scoring system and embedded data before, but couldn't find a way to dynamically divide by the number of areas chosen without using JS.


I am open to suggestions on how to achieve this in a better way, but executing the above code reliably is my primary concern now.

@CanerLC,

Honestly, it would be a heck of a lot of work to recreate your survey and debug your JavaScript. That's probably why there hasn't been any response. If someone were to take it on, it would be helpful if you posted a .qsf of your survey to at least give them a starting point.
