Hi all,
Is there any way to edit the equation of the total box in constant sum questions? For example, instead of the total box showing [X+Y], I'd like it to show [X-Y]. I know I could just have my respondents input a negative number for "Y", but they fill out this survey regularly and have always input a positive number for Y. Right now, I have it as a text entry matrix where the respondents have to manually input the total and it always ends up being a little off.
Thanks in advance!

Hello JacquelineS
This code should work
Qualtrics.SurveyEngine.addOnReady(function () {
var $this = jQuery(this.questionContainer);
var total, inputVal;
jQuery(".QuestionBody .SumInput input", $this).on("input", function () {
total = 0;
jQuery(".QuestionBody .SumInput input", $this).each(function (i) {
inputVal = jQuery(this).val();
if (inputVal && inputVal.trim().length > 0 && !isNaN(inputVal)) {
total = i === 0 ? parseFloat(inputVal) : (total - parseFloat(inputVal));
}
});
jQuery(".QuestionBody .SumTotal input", $this).val(total);
});
});

https://www.qualtrics.com/community/discussion/comment/34389#Comment_34389This looks amazing and works perfectly for constant sums! ChiragK do you know of a way to change this for matrix constant sums. I'd love to have 4 statements and 2 scale points with the total being scale point 1 minus scale point 2 for each statement.
