Excellent! I see you corrected the fundamental issue with the data reference as well - you have changed [image] taaddele: timerElement.textContent ='${math.ceil(data.remaining_time)} seconds' ^^^^^^^^^^^^^^ to [image] taaddele: timerElement.te…

What is the name of the key in the json structure that you are sending to the browser? What is the name of the key that you are looking for in your JavaScript?
