Dear All, @TomG,
I am trying to validate a SBS question by using custom validation. However, the page reloads whenever the validation fails. This causes the JS codes to reload as well, and mess up the revealing sequence of the statements and columns. Below is the code with some descriptions of what it is meant to do. Could anyone advise how I could recover the page whenever the validation fails and the page reloads? Thank you.
Qualtrics.SurveyEngine.addOnload(function()
{
this.hidePreviousButton();

var elements = parseInt("${e://Field/sceneA}");
elements = elements + 1;
Qualtrics.SurveyEngine.setEmbeddedData('sceneA', elements);
});


Qualtrics.SurveyEngine.addOnReady(function () {
