1) Loop through array of sheet/file IDs 2) Use DriveApp to getLastUpdated for each file 3) setValues in adjacent column

The log spits out the information that I want (a timestamp of when the file was last updated), but when trying to setValues() in the adjacent column, I get "Exception: The parameters ((class)) don't match the method signature for SpreadsheetApp.Range.setValues."

function getLastModified() {  var ss = SpreadsheetApp.getActiveSpreadsheet();  var getTab = ss.getSheetByName("Tab1");  var sheetID = getTab.getRange("L2:L101").getValues();  var pasteRange = getTab.getRange("K2:K101");  for (i=0;i<sheetID.length;i++){     if(sheetID[i] == ""){     } else {      var file = DriveApp.getFileById(sheetID[i]);      var date = file.getLastUpdated();//      pasteRange.setValues(date);//the log worksLogger.log(date)     }     }  }
