Having trouble save my output file as name based on cell from spreadsheet in google apps scripts

Question

Here's my code which was done mostly by a much talented coder then me:

function SaveSpreadsheetAs(){
  
var Sheet=SpreadsheetApp.getActiveSpreadsheet();
var Peter=Sheet.getSheetByName("Peter");        
var Filename=Peter.getRange(2,2,1,1).getValue();
  //Folder to save pay periods on google drive
 var destFolder = DriveApp.getFolderById("es3424kbjb4j32wbryujb3r"); 
              
 DriveApp.getFileById("093hnweuibf2873bfuiww").makeCopy(Filename,destFolder); 

 }

My question is why is (var Filename)'s output not the value of the B2 cell from the sheet name "Peter"? I know I am making a very basic level mistake as I am very new to this but what am I missing. The code works if you change the (var Filename) with a text entry. Thank you in advanced.

I ran it this way. It runs fine.

function SaveSpreadsheetAs() {
  const ss = SpreadsheetApp.getActiveSpreadsheet();
  const sh = ss.getSheetByName(gobj.globals.targetsh);
  const Filename = Utilities.formatDate(new Date(sh.getRange(2, 2).getValue()),ss.getSpreadsheetTimeZone(),"MMM-dd-yyyy HH:mm:ss");
  const destFolder = DriveApp.getFolderById(gobj.globals.testfolderid);
  const file=DriveApp.getFileById(gobj.globals.testsourceid).makeCopy(Filename, destFolder);
  Logger.log(file.getName());
}
