Keeping the dynamic url the way it is???

[cturner]

Can someone please tell me how I can keep a query string in the url? In my code I have a part where if a user leaves out a field or two on a form it will display messages on that page where the query string is and when the user clicks on a button the query string disappears from the url. I don't want the query string to disappear. Thanks in advance.

Here is the code for checking to see if the combo boxes are selected or not, etc:
[code]
$selectpacksize = $_POST['selectpacksize'];
$selectcolour = $_POST['selectcolour'];
$selecticon = $_POST['selecticon'];
$nameprint = $_POST['nameprint'];
$username = $_COOKIE['username'];
$address1 = $_POST['address1'];
$address2 = $_POST['address2'];
$address3 = $_POST['address3'];
$address4 = $_POST['address4'];
$address5 = $_POST['address5'];
$arrErrors = array();

if (isset($_POST['order'])) {
if ($selectpacksize == 'none') {
$arrErrors['selectpacksize'] = 'Please select a pack size.';
}

//if (!empty($row['colour'])) {
if ($selectcolour == 'none') {
$arrErrors['selectcolour'] = 'Please select a colour.';
}
//}

//if (!empty($row['icon'])) {
if ($selecticon == 'none') {
$arrErrors['selecticon'] = 'Please select an icon.';
}
//}

// check to see if the product exists in the cart table
$sql = mysql_query("SELECT * FROM `tbl_cart` WHERE `username` = '$username' AND `pd_id` = '$pd_id'") or die ("Could not query because: ".mysql_error());

$check = mysql_num_rows($sql);

if ($check >= 1) {
// if the product is in the database then increase the quantity
$insertqty = "UPDATE `tbl_cart` SET `ct_qty` = `ct_qty + 1` WHERE `username` = '$username' AND `pd_id` = '$pd_id'";

}

if (count($arrErrors) == 0) {
// today's date
$date = time();

$query2 = "SELECT * FROM `tbl_product` WHERE `pd_id` = '$pd_id'";
$r2= mysql_query($query2) or die('Query error: ' .mysql_error());
$row2= mysql_fetch_assoc($r2);
$pd_id = $row2['pd_id'];

$insertproduct = "INSERT INTO `tbl_cart` (`ct_id`, `ct_qty`, `ct_date`, `username`, `pd_id`, `packsize`, `colour`, `icon`, `name`, `address1`, `address2`, `address3`, `address4`, `address5`) VALUES (0, 'ct_qty + 1', '$date', '$username', '$pd_id', '$selectpacksize', '$selectcolour', '$selecticon', '$nameprint', '$address`', '$address2', '$address3', '$address4', '$address5')";

if (mysql_query ($insertproduct)) {
header ('Location: viewcart.php');
} else {
print "<p>Could not add the entry because: <b>" . mysql_error() . "</b>. The query was $insert.</p>";
}

} else {
        // The error array had something in it. There was an error.
        // Start adding error text to an error string.
        $strError = '<div class="formerror"><p>Please check the following and try again:</p><ul>';
        // Get each error and add it to the error string
        // as a list item.
        foreach ($arrErrors as $error) {
            $strError .= "<li>$error</li>";
        }

Before I click on the order button it starts off at [url=http://www.blueguminteractive.biz/example1.htm]this page[/url]. Then when I click on the order button and when the combo boxes aren't selected it goes to [url=http://www.blueguminteractive.biz/example2.htm]this screenshot[/url].
