The problem is that we see the variables in the URL, but it is empty in the body of the script:

URL: "http://localhost/inst_add_assig.php?sec=99&co=9990"

page: inst_add_assig.php

include 'include.inc';

if (empty($assigTitle)){

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<title>Add an Assignment</title>
<link rel="stylesheet" href="style.css" type="text/css">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="JavaScript" type="text/JavaScript">
function MM_reloadPage(init) {  //reloads the window if Nav4 resized
  if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
    document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}
  else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();

<body bgcolor="#FFFFe8">

<div id="Layer1" style="position:absolute; left:0px; top:0px; width:508px; height:52px; z-index:1"><img src="logo/eSubmissionbannerBigLighter.jpg" width="783" height="69"></div>
<?php echo"
<form name=\"form1\" method=\"post\" action=\"inst_add_assig.php?co=".$co."&amp;sec=".$sec." enctype=\"multipart/form-data\">";?>
<input type="hidden" name="MAX_FILE_SIZE" value="1000000">

  <table width="75%" border="0" align="center">
      <td><strong>Enter file name:</strong></td>
      <td><input type="file" name="uploadedFile" class="textfield"></td>
      <td><strong>Enter assignment title:</strong></td>
      <td><input type="text" name="assigTitle" class="textfield"></td>
      <td height="26"><strong>Due date:</strong></td>
      <td> <select name="select" class="select">
        </select> <select name="select2" class="select">
        </select> <select name="select3" class="select">
        </select> </td>
      <td height="21"><strong>Files to be included:</strong></td>
      <td height="21"><input type="text" name="textfield3" class="textfield"></td>
      <td height="113" colspan="2"><div align="center">
            <input type="submit" >


else if (!empty($assigTitle))

if($HTTP_POST_FILES['uploadedFile']['size'] <=0)
    print"<b>Not recieved.</b><br>";
      //$sect= $sec;
        //$cour= $_POST['courseName'];
      $username = strtolower($_SESSION["loginUsername"]);
      $dir =  "instructor/" . $username . "/" . $assig . "/";
        echo "***".$sec."***".$co;
        //$username = strtolower($_SESSION["loginUsername"]);
      $destination=  "instructor/" . $username . "/". $assig . "/".$HTTP_POST_FILES['uploadedFile']['name'];
      echo "******". $destination;


When pressing the submit button, the page will alwayes consider the statement "if (empty($assigTitle))" true
and I get the following URL

instead of adding the variables in the action part of the form tag
create hidden inputs inside your form

<form method="POST" action="inst_add_assig.php">
.. rest of form stuff
<input type="hidden" name="co" value="<?=$co?>">
<input type="hidden" name="sec" value="<?=$sec?>">

also i cant see where $assigTitle is getting initialised???

should you not have something like

$assignTitle = $_POST["assigTitle"];

before the if statment
