Hi ​@DashaG ,

Did you change the QID number to fit your situation?

I placed the following JavaScript code, from the thread you mentioned, into question QID36 (item 1)’s Add JavaScript. Then, question QID37 (Item 2) having in-page display.

It is working, where the next button is hidden when Item 2 is not displayed.

Qualtrics.SurveyEngine.addOnReady(function()
{
	jQuery("#NextButton").hide();
	jQuery(".JFE").on("mouseover change click", function(){
    jQuery("#NextButton").hide();
    /*Change QID37 to your question*/
    if (jQuery("#QID37").is(":visible")){
        jQuery("#NextButton").show();
    }else{
        jQuery("#NextButton").hide();
    }})}
);

If it still doesn’t work on your end, perhaps you might be using New Survey Experience.

Simple layout would be something like this :

Qualtrics.SurveyEngine.addOnReady(function () {
  var nextButton = document.getElementById("next-button");
  if (nextButton) nextButton.style.display = "none";
  var pages = document.querySelectorAll("#page");
  pages.forEach(function (el) {
    ["mouseover", "change", "click"].forEach(function (evtType) {
      el.addEventListener(evtType, function () {
        if (nextButton) nextButton.style.display = "none";
        var qid2 = document.getElementById("question-QID2");
        if (qid2 && qid2.offsetParent !== null) {
          nextButton.style.display = "flex";
        }
      });
    });
  });
});
