I am running this code as a custom button. When this button is used by anyone to create a copy of the current sheet i want the original and the new sheet to be owned by the original owner of the sheet (and all permissions to be intact)

function newVersion() {

  var confirm = Browser.msgBox("Create new Version?", Browser.Buttons.YES_NO); 

  if(confirm!="yes"){return};

  var ss = SpreadsheetApp.getActiveSpreadsheet();

  ss.setActiveSheet(ss.getSheetByName("Budget Estimate (Internal)"));

  var currName = SpreadsheetApp.getActiveSpreadsheet().getName();

  var oldVer = ss.getRange("B2").getValue();

  var oldVerNum = oldVer.substr(1,1);

  var numVer = parseInt(oldVerNum);

  var numNew = (numVer + 1);

  var newVer = ("V"+numNew);

  var newDate = Utilities.formatDate((ss.getRange("E4").getValue()), "GMT+10", "yyyyMMdd");

  var newName = "Budget Estimate "+ss.getRange("E3").getValue()+" "+newVer+" "+newDate;

  ss.rename("tempSheetName");

  var directParents = DriveApp.getFileById(ss.getId()).getParents();

    while (directParents.hasNext()){

      var folderID = directParents.next().getId();

    }

    

  var destFolder = DriveApp.getFolderById(folderID);  

  var master = DriveApp.getFileById(ss.getId());

  var newFile = master.makeCopy(currName, destFolder);

  

  ss.rename(newName);

  ss.setActiveSheet(ss.getSheetByName("Budget Estimate (Internal)"));

  SpreadsheetApp.getActiveSheet().getRange("B2").setValue(newVer);

}
