Hi all, I'm trying to do maths calculations on click so that they appear in the matrix table as below using JavaScript. I also need to restrict the user to not be able to enter anything into the calculation fields. Has anyone done anything similar before and have any code as a starting point? ! Thanks, Rose

Hi Rose,This is the solution I came up with - should also take care of and NaN errors by defaulting these values to 0.Qualtrics.SurveyEngine.addOnReady(function() {this.questionclick = function(event,element){var i =0; /*Setting column number for loopage*/while (i<6){var a = parseInt(this.getChoiceValue(2,i),10);var b = parseInt(this.getChoiceValue(3,i),10);/*default NaN to 0 */if(isNaN(a)){ a= 0;}if(isNaN(b)){ b= 0;}var x = a+b ;/*Set Value*/this.setChoiceValue (4,i,x);var y = parseInt(this.getChoiceValue(5,i),10)/parseInt(this.getChoiceValue(4,i),10);if(isNaN(y)){ /*check if div by 0*/y = 0;} /*Set Value*/this.setChoiceValue (6,i,y);/*Increase column number*/i++;}} });

Hi @rose_b Please read this post it may help you to write codehttps://www.qualtrics.com/community/discussion/926/side-by-side-question-constant-sum-and-auto-complete-dropdown
