Javascript not quite working as intended. Help needed

Hi Everyone, I am using some javascript that allows for radio buttons to be de-selected. The issue I am having is that Qualtrics is still saving the original response even after it is deselected. Does anyone know how to fix this? `Qualtrics.SurveyEngine.addOnload(function() { //initialize values var prevValue = ''; var exampleForm = document.forms['Page']; var labels = document.getElementsByTagName('LABEL'); //question click is a simple onclick handler //attached to the question's container div this.questionclick = function(event,element) { //by default you get the click event as the first parameter and the clicked element as the second parameter if (element.type == 'radio') { //check if the radio was pressed in a row if (element.id == prevValue) { for (var i = 0; i < labels.length; i++) { if (labels[i].htmlFor == element.id) { labels[i].className = labels[i].className.replace( /(?:^|\\s)q-checked(?!\\S)/g , '' ); labels[i].className = labels[i].className.replace( /(?:^|\\s)q-focused(?!\\S)/g , '' ); } } for( var i=0; i<exampleForm.length; i++ ){ //once found, uncheck it if(exampleForm[i].id == element.id) { exampleForm[i].checked=false; } } //clear temp value prevValue = ''; } else { //make last pressed button this one prevValue = element.id; } } } });`
