In the attached photo, I have a matrix question. I’m looking for some JavaScript so that a future question will only appear if at least 2 shows are selected. It does not matter if the boxes selected are computer, mobile, or tablet. Regular Qualtrics display logic gets massive. Qualtrics support suggested I ask the community about a JavaScript option.

Here’s the solution: Put this javascript into the Matrix question on the survey. Then go to the survey flow, and create an embedded field data, called“hasTwoOrMoreProducts” = Yes. Make sure this embedded field is on the top of the survey flow. Then for the questions where you only want the question to show if 2 or more products are selected, select the displaylogic on that question, thenselect “hasTwoOrMoreProducts” = yes. It works.Qualtrics.SurveyEngine.addOnload(function() { const questionId = this.questionId // function to check matrix selection function checkMatrixSelection() { const matrix = jQuery("#"+ questionId +" table.ChoiceStructure tbody tr") var uniqueProductCount = 0; // loop through each row of the matrix to count unique product selections matrix.each(function() { const selected = jQuery(this).find('input:checked'); if (selected.length >= 1) { uniqueProductCount++; } }); // Show or hide Question 2 based on unique product count if (uniqueProductCount >= 2) { console.log('more than 2') Qualtrics.SurveyEngine.setEmbeddedData('hasTwoOrMoreProducts', 'Yes') } else { console.log('less than 2') Qualtrics.SurveyEngine.setEmbeddedData('hasTwoOrMoreProducts', 'No') } } // Add event listener to all matrix inputs jQuery(this.getQuestionContainer()).on('change', 'input[type=checkbox]', function() { checkMatrixSelection(); }); // Initial check in case the user navigates back checkMatrixSelection();});

Thanks for this code. I needed something similar, and was able to use this. It works!
