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'
