I use this code in JavaScript to hide the PreviousButton on a page: Qualtrics.SurveyEngine.addOnload(function() { jQuery("input#PreviousButton.PreviousButton.Button").css("display", "none"); }); I use this code on the first question of the block, no page break, and put it in addOnload, addOnready, addOnunload. However, one of the question has a validation parameter. When this validation is not met and the NextButton is pressed, the page reloads and the PreviousButton is back. Why is that so and how to fix it?
