Running multiple onEdit scripts

Question

I am trying to run all three of these in any order but only the third runs:

1.

function onEdit(){
  var sh = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var editedCell = sh.getActiveRange().getColumnIndex();

  if(editedCell == 10) { 
    var range = sh.getRange("A:O");
    range.sort([{column: 1}, {column: 14, ascending: true}, {column: 5, ascending: false}]);
  }
}

2.

function onEdit() {
  var sheetName = "PRE-APPRAISAL";
  var s = SpreadsheetApp.getActiveSheet();
  if (s.getName() !== sheetName) return;
  var r = s.getActiveCell();
  if( r.getColumn() != 'J' ) { //checks the column
    var row = r.getRow();
    var time = new Date();
    time = Utilities.formatDate(time, "GMT-08:00", "MM/dd/yy, hh:mm");
    SpreadsheetApp.getActiveSheet().getRange('H' + row.toString()).setValue(time);}
  }

3.

function onEdit() {
  var sheetName = "POST-APPRAISAL";
  var s = SpreadsheetApp.getActiveSheet();
  if (s.getName() !== sheetName) return;
  var r = s.getActiveCell();
  if( r.getColumn() != 'J' ) { //checks the column
    var row = r.getRow();
    var time = new Date();
    time = Utilities.formatDate(time, "GMT-08:00", "MM/dd/yy, hh:mm");
    SpreadsheetApp.getActiveSheet().getRange('H' + row.toString()).setValue(time);}
  }

Answer 1

That occurs because there could only be one function called onEdit() by Google Apps Script Project.

Change their names to myFunction1, myFunction2, myFuntion3 or anything else but using a unique name for each function, then make a onEdit() function that calls them something like the following:

function onEdit(){
  myFunction1();
  myFunction2();
  myFunction3();
}
