Hi,I’m new to this, so please be patient! I’m trying to get a single response option for a matrix table to appear as a radio button instead of a fill in the blank option as a “don’t know” option. But I can only seem to get qualtrics to give me all fill in the blank response options or all radio buttons. The rest of the responses for that question need to be validated as numbers so I need to use a matrix table so I can have the custom validations. I think my question id is ${q://QID91}. I’m having trouble understanding if that’s the correct way to insert a question id into javascript options in Qualtrics. Could someone help give me an example of the code with the question id already in there so I don’t have to replace the question id? I tried generating some code from chatgpt but it hasn’t worked at all. Basically, I’d like it to look like the below except the “last” response option would be the radio circle button. Please help I’ve been stuck for hours. (also I’m sorry I can’t seem to edit the post title after it posted)

Hi, I was able to follow TomG's recommendation to hide the last text input and update its value with "1" if an inserted checkbox is selected. To give it a try, set the survey to Flat layout and create a Matrix question that is set to Text Entry, has 4 statements, 1 scale point, and text box size set to large. Then, add the below to the question's JavaScript in the OnReady section:var qid = this.questionId;//increase Matrix Text Entry size//jQuery("#"+qid+" td input").css({"width": "90%"});//identify last text input//jQuery("#"+qid+" td input:last").attr('id','lasttext');var lasttext = document.getElementById('lasttext');//create checkbox and append after last text input//jQuery('<input type="checkbox" name="NA" id="NA" class="NAclass">').insertAfter(lasttext);var na = document.getElementById('NA');jQuery(na).css({"position": "relative","opacity": "1","z-index": "999","height": "20px","width": "20px"});jQuery(lasttext).css({"display": "none"});//default value to 0//jQuery(lasttext).val("0");//change to 1 when checkbox is clicked//jQuery(na).click(function () {if( jQuery(na).is(":checked") ) { jQuery(lasttext).val("1"); } else { jQuery(lasttext).val("0"); }});

Insert the question id in your JavaScript as this.questionId. For example:Qualtrics.SurveyEngine.addOnload(function() { var q = jQuery("#"+this.questionId);});As for what you are trying to do, you can’t mixed radio buttons and text inputs in a Matrix. You can add your own checkbox(it will work better than a radio button) with JavaScript and hide the text input, then update the text input to 1 if the checkbox is clicked.
