document.getElementById("time").addEventListener("change", function() {
  var selectedValue = this.value;
  var minutesOptions = document.querySelectorAll("#time option");
  
  for (var i = 0; i < minutesOptions.length; i++) {
    if (minutesOptions[i].value !== selectedValue) {
      minutesOptions[i].disabled = true;
    } else {
      minutesOptions[i].disabled = false;
    }
  }
});
