Need to refresh the php contained within a div

i have a calendar page that has a popup contained in a div.  the div has php code to include 'scheduler.php' which retrieves data from MySQL.  an onClick call launches the popup.  i need 'scheduler.php' to refresh with the variable that defines from which square the user is launching the popup.  

i would then use that variable in a MySQL query.  the variable is in my popup opener script as 's_box.value'.  i have successfully used ajax to pass this variable to a backend php script for writing to the database.  but i can't figure out how to make scheduler.php in the popup refresh with the updated php variable because the php script is already loaded when the main page loads.
//javascript popup launcher
function fireMyPopup_2(the_session) {
var session = the_session;
 document.getElementById("mypopup2").style.display = "block";
//set hidden 'session' variable in form
var s_box = document.getElementById('session_box');
  s_box.value = session;
  document.schedule.reset();
}
//onClick handler that passes calendar box variable to javascript
<a href="#" onClick='fireMyPopup_2(<?php $session = $i+1 . '.3'; echo $session; ?>)'>
 //the div
<div id='mypopup2' name='mypopup2'
