I have assigned the functions to the pictures. But I don’t understand why the function always takes the last else. Could someone help me?
Thank you very much!

why

var mondayClearAb = timeStamp.getRange(7, 2);
var tuesdayClearAb = timeStamp.getRange(8, 2);
var wednesdayClearAb = timeStamp.getRange(9, 2);
var thursdayClearAb = timeStamp.getRange(10, 2);
var fridayClearAb = timeStamp.getRange(11, 2);
var saturdayClearAb = timeStamp.getRange(12, 2);
var sundayClearAb = timeStamp.getRange(13, 2);

var mondayClearAe = timeStamp.getRange(7, 3);
var tuesdayClearAe = timeStamp.getRange(8, 3);
var wednesdayClearAe = timeStamp.getRange(9, 3);

    var newTime = new Date();

}

  if (i < 10) {
    i = "0" + i;

  var timeStamp = SpreadsheetApp.getActiveSheet();
  var time = new Date();
  var hours = addZero(time.getHours());

    timeStamp.getRange(7, 2).setValue(hours + ":" + minutes + ":" + seconds); 
    }
