PHP Header(location: mypage.php) directive causes page to crash

I have a corporate Intranet page that asks the user to select a bunch of data to modify by selecting dropdown items and checking off boxes.
The selection is all done in a form.
Upon clicking 'Submit', the page calls itself as an action and validates that at least one checkbox has been checked.  If so, I am okay to go to the next page.
The page works well for data validation, and if I uncomment the echo statements I can see the session varibales that are being set as a a result of data selection.
If i uncomment the header ("location: ....) line, the page crashes.

Any idea what is going on?

    //ini_set('error_reporting', E_ALL);                                      
    session_start();
    include '../Include_Files/ServerSide/connect_qisuser.inc';
    $err = "";
    $shortItems = '';
    $lines_total = count($_SESSION['model_array']);
    
    // If user has submitted form
    if(isset($HTTP_POST_VARS["Submit"])) {
        //$lines_total = count($_SESSION['model_array']);
        //echo $lines_total . "<br />";
        for ($i = 0; $i <= $lines_total; $i++) {
            if (isset($HTTP_POST_VARS["check".$i])) {
                if ($shortItems === '') {
                    $shortItems = $HTTP_POST_VARS["check".$i];
                    $newModelArray = $_SESSION['model_array'][$i];
                }
                else {
                    $shortItems .= "|" . $HTTP_POST_VARS["check".$i];
                    $newModelArray .= "|" . $_SESSION['model_array'][$i];
                }
            }
        }
        
        //echo "<br /><br /><br />";
        //print_r ($shortItems);
        //echo "<br />";
        //print_r ($newModelArray);
        //echo "<br />";
        
        
        if ($shortItems === '') {
            $err = "<br /><br />You must select at least one item to update.";
        }
        
        else {
            $sels = '';
            for ($i=1;$i<21;$i++) {
                if ($sels === '') {
                    $sels = $HTTP_POST_VARS["sel".$i];
                }
                else {
                    $sels .= "|" . $HTTP_POST_VARS["sel".$i];
                }
            }
            
            $_SESSION['shortItems'] = $shortItems;
            $_SESSION['newModelArray'] = $newModelArray;
            $_SESSION['sels'] = $sels;
            //echo "<br /><br />" . $_SESSION['shortItems'] . "<br />";
            //echo $_SESSION['newModelArray'] . "<br />";
            //echo $_SESSION['sels'] . "<br />";
            //header("Location: update20fields.php");
        }        
    }

If I leave the line in, the page reloads with no issues.

There is no output sent to the screen upon POSTing the form.
The script just processes form elements, assigns session varibales and is supposed to redirect to the next page for further processing.

THAT'S IT!

What was throwing me off was that when I right-clicked on the error page and checked the properties it showed be the address of the calling page, not the destination page!

Thank you!
