Loop through a column and change value of another column based on cell values in Google Apps Script

Question

The following script should change cell values in column K based on values in column D. However, the comparator is not working, it always returns "NO".

Is range.toString the correct syntax? I think I'm not comparing Apples to Apples.

function Test1() {

   var ss = SpreadsheetApp.getActiveSpreadsheet();
   var s = ss.getSheetByName("report");
   var numRows = SpreadsheetApp.getActiveSheet().getLastRow();
   var range;

  /* Loop through Column D and find cells equal to order payment
  and set Column K value based on it */

   for (var i = 1; i <= numRows; i++) {
      range = s.getRange('D' + i );
      if (range.toString() == "Order Payment") {
        range.offset(0, 6).setValue("YES"); 
      }
     else {
       range.offset(0,6).setValue("NO");
     }
   }
}

Answer 1

range.getValue() == "Order Payment"是正确的语法，而不是range.toString()
