Google sheets 谷歌工作表-让脚本只影响一个工作表，而不是所有工作表

我肯定我做错了什么，但我不知道是什么。下面的代码影响我的所有工作表，而不仅仅是我希望它影响的“管道”工作表

function onEdit() {
   var ss = SpreadsheetApp.getActiveSpreadsheet();
   var s1 = ss.getSheetByName("Pipeline");
   var r = s1.getActiveCell();

if(r.getColumn() === 3, r.getValue()==='Closed' ) {
  var nextCell = r.offset(0, 6);
  var printPipeline = r.offset(0,1);
  var digitalPipeline = r.offset(0,2);
  var propelPipeline = r.offset(0,3);
  printPipeline.clearContent(), digitalPipeline.clearContent(),propelPipeline.clearContent() ;
  if( nextCell.getValue() === '')//checks for blank cell
  nextCell.setValue(new Date())}
else if( r.getColumn() == 3, r.getValue()==='Lost' ) {
  var nextCell = r.offset(0, 7);//offset (row,column)
  var closedCell = r.offset(0, 6);
  var pProductsCell = r.offset(0,8);
  var pRevCell = r.offset(0,9);
  var pLengthCell = r.offset (0,10);
  var dProductsCell = r.offset(0,12);
  var dRevCell = r.offset(0,13);
  var dLengthCell = r.offset (0,14);
  var prProductsCell = r.offset(0,16);
  var prRevCell = r.offset(0,17);
  var prLengthCell = r.offset (0,18);
  closedCell.clearContent(), pProductsCell.clearContent(), pRevCell.clearContent(), pLengthCell.clearContent(), dProductsCell.clearContent(), dRevCell.clearContent(), dLengthCell.clearContent(), prProductsCell.clearContent(), prRevCell.clearContent(), prLengthCell.clearContent();      
  if( nextCell.getValue() === '')//checks for blank cell
  nextCell.setValue(new Date())}}

为图纸名称添加检查，如果不等于“管道”，则返回：

   var ss = SpreadsheetApp.getActiveSpreadsheet();
   var name=ss.getSheetName()
   if(name!="Pipeline"){return}

非常感谢你！你真是天赐之物！
