Update Variable if Next Button is clicked

Hi @anleta ,

Yes it is possible ,  please add below code :
 

Qualtrics.SurveyEngine.addOnload(function()
{
	/*Place your JavaScript here to run when the page loads*/

});

Qualtrics.SurveyEngine.addOnReady(function()
{
	/*Place your JavaScript here to run when the page is fully displayed*/
document.getElementById('NextButton').addEventListener("click", setValue);
      function setValue() {

 Qualtrics.SurveyEngine.setEmbeddedData('count', 1);
      }
});

Qualtrics.SurveyEngine.addOnUnload(function()
{
	/*Place your JavaScript here to run when the page is unloaded*/

});

Hope this resolves your query😊!!

We can write the JS  in the survey header which increments an embedded data on click of next button.
