Can't read $_POST[] value from a PHP form

<?php
echo "<form action='bossconfirm2.php' method='post' name='bossex' onsubmit='blankCheck()' >";

echo "<td><select id='disapprove".$i."' name = 'sel".$i."'>
              <option value = '".$row['LeaveID']."'>Approve</option>
              <option value = '2'>Disapprove</option>
          </select>".$i."</td>";

My Code goes something like the one above. I'm trying to pass the value of sel+$i (which would be sel1 when concatenated) to the php file bossconfirm2.php. Here's my code for bossconfirm2.php:

$se11 = $_POST['sel1'];
$se12 = $_POST['sel2'];
$se13 = $_POST['sel3'];
$test = $_POST['test'];

echo "HI<br>";
echo "<br> ".$test."<br>";

echo "Sel 1 <br>".$sel1."Sel 2<br>".$sel2."Sel 3 ".$sel3;

Whenever the I display the values for $sel1, nothing appears. I placed an echo "HI

"; to see if there's something wrong with the PHP syntax but I've discovered that the $_POST[] just can't access the form. I tried adding an html syntax at the end of the file to see if I could pass a value to $test with this code

<td><input type='text' name='test'></td>

and it worked. It seems that the form I created using pure PHP (echo ..etc) can't pass values. Somebody please enlighten me as to how I could make it work?

Edit: Here's my complete code

<?php
echo "<form action='bossconfirm2.php' method='post' name='bossex' onsubmit='blankCheck()' >";

include 'config.php';
include 'opendb.php';

$testing = $_REQUEST['parent_id'];

$appSql = "SELECT f.LeaveId, CONCAT(p.LastName, ', ', SUBSTRING(p.Firstname,1,1), '.') 'Name',

$appSqlQ = mysql_query($appSql) or die(mysql_error());

    echo "<td bgcolor = '888888'>Name</td>";
    echo "<td bgcolor = '888888'>From</td>";
    echo "<td bgcolor = '888888'>To</td>";
    echo "<td bgcolor = '888888'>Leave Type</td>";
    echo "<td bgcolor = '888888'>Reason</td>";

    $i = 1;
    while($row = mysql_fetch_array($appSqlQ))

                echo "<td>" . $row['Abbreviation'] . "</td>";                
                echo "<td bgcolor = 'FFF111'>" . $row['Reason'] . "</td>";

                echo "<td><select id='disapprove" . $i . "' name = 'sel" . $i . "'>

echo "</tr>";
}                 
echo "</form>";


?>
<td><input type='text' name='test'></td>

And here's my code for bossconfirm.php

<?php
include 'config.php';
include 'opendb.php';
session_start();
$sessionID = $_SESSION['id'];
$x = 0;
$checkValue = $_POST['value'];

$sel1 = $_POST['sel1'];
$sel2 = $_POST['sel2']; 
$sel3 = $_POST['sel3']; 
$test = $_POST['test'];

echo "HI<br>";
echo "<br> " . $test . "<br>";

echo "Sel 1 <br>" . $sel1 . "Sel 2<br>" . $sel2 . "Sel 3 " . $sel3;

$today = date('Y-m-d');
?>

One way to keep a check on what's being posted is the print_r($_POST) function which will print the array of post values.

You could also wrap this in pre tags as follows to format the output in a more readable form such as

<pre>
<?php print_r($_POST); ?>
</pre>
