POST Variables not being passed

I'm trying to pass some POST variables from hidden inputs (using JQuery to change the value of the input according to the text in the td field). I've tested the JQuery and it definitely assigning the inputs the right values, but when I try and assign POST variables according to the values on the previous page, they're not set to the numbers.

Code:

<form method="POST" action="newcriminalreport2.php"> <div style="width:800px;text-align:left;margin:0 auto;padding-bottom:5px;">A. PENDING BALANCE</div> <table border="1" style="width:800px;" ID="tableA"> <th style="width:40%;"></th> <th colspan="2" style="width:20%;">CAPITAL</th> <th colspan="2" style="width:20%;">NON-CAPITAL</th> <th colspan="2" style="width:20%;">TOTAL</th> <tr> <td></td> <td>Defs</td> <td>Cases</td> <td>Defs</td> <td>Cases</td> <td>Defs</td> <td>Cases</td> </tr> <tr> <td>1.

and the next page:

<?php session_start(); $judge = $_SESSION['judge']; if(!isset($_SESSION['user'])){ header( 'Location: index.php' ); die(); } // Get line 1 and 5 from first page (to be used in newcriminalreport3 totals) $_SESSION['PendingCapDefs'] = $_POST['PendingCapDefs']; $_SESSION['PendingCapCases'] = $_POST['PendingCapCases']; $_SESSION['PendingNonCapDefs'] = $_POST['PendingNonCapDefs']; $_SESSION['PendingNonCapCases'] = $_POST['PendingNonCapCases']; $_SESSION['PendingDefsTotal'] = $_POST['PendingDefsTotal']; $_SESSION['PendingCasesTotal'] = $_POST['PendingCasesTotal']; $_SESSION['PendingCapDefsTotal'] = $_POST['PendingCapDefsTotal']; $_SESSION['PendingCapCasesTotal'] = $_POST['PendingCapCasesTotal']; $_SESSION['PendingNonCapDefsTotal'] = $_POST['PendingNonCapDefsTotal']; $_SESSION['PendingNonCapCasesTotal'] = $_POST['PendingNonCapCasesTotal']; $_SESSION['PendingTotalDefs'] = $_POST['PendingTotalDefs']; $_SESSION['PendingTotalCases'] = $_POST['PendingTotalCases']; ?> 

Anyone know what's up?

print_r($_POST):
