Google Apps脚本数据验证代码不起作用

Question

Could you please help get the dataValidation part of the code working? All the other parts of the code is working, only the dataValidation part is not working unfortunately.

Here is the code: // "Ready Line" formats word in column J

     if (r.getColumn() == 10 && e.value == "A Ready Line") {
      sheet.getRange(r.getRow(),r.getColumn()).setBackgroundColor("#FFFF00");
      sheet.getRange(r.getRow(),r.getColumn()).setFontColor("#38761d");
      var rule = SpreadsheetApp.newDataValidation().requireValueInRange(['B Hold', 'C Confirm']).build();
      sheet.getRange(r.getRow(),r.getColumn()).setDataValidation(rule);
   // Timestamp column CG  
      sheet.getRange(r.getRow(),r.getColumn()+75).setValue(new Date());
   // Clear columns MtoAA,   
      sheet.getRange(r.getRow(),r.getColumn()+3,1,15).clearContent();
        }

You should use requireValueInList instead of requireValueInRange:

var rule = SpreadsheetApp.newDataValidation().requireValueInList(['B Hold', 'C Confirm']).build();

Also setBackgroundColor is depreciated. As well you can simplify your code by using this:

var rule = SpreadsheetApp.newDataValidation().requireValueInList(['B Hold', 'C Confirm']).build();

sheet.getRange(r.getRow(),r.getColumn())
  .setBackground("#FFFF00")
  .setFontColor("#38761d")
  .setDataValidation(rule);
