Tutorial Dreamweaver Cs5.5 The Missing Manual (Pg 998 - 1018) about adding dynamic data to your page

Question

Hallo,
I did Tutorial: Displaying Database Info in the Missing Manual for Dreamweaver CS5.5.
My problem is with "Editing a Recordset and Linking to a Detail Page" (which starts at pg 1002:
I did this exercise ,over 5 times nowe, but every time with "Building the Detailed Product Page" at pg 1007, I get a bad result.
I only get one page (the default one with productID = 1) for every link on the indexpage.
In the adressbar (Live View) I see the right adress: for example: http://localhost/cos...hp?productID=16, but for all productID's only the detailspage for productID are shown.
There is also a message: Notice: Use of undefined constant ‘productID’ - assumed '‘productID’' in E:\xampp\htdocs\cosmo_shop\product.php on line 34
But I don't understand what could be wrong in this line.
Here is the code lines 33 -48: is is about the second line:
$varProduct_rsDetails = "32";
if (isset($_GET[‘productID’])) {
  $varProduct_rsDetails = $_GET[‘productID’];
mysql_select_db($database_connCosmo, $connCosmo);
$query_rsDetails = sprintf("SELECT products.productID, products.productName, products.price, products.`description`, products.inventory, products.image, vendors.vendorName FROM products, vendors WHERE products.vendorID = vendors.vendorID AND products.productID = %s ", GetSQLValueString($varProduct_rsDetails, "int"));
$rsDetails = mysql_query($query_rsDetails, $connCosmo) or die(mysql_error());
$row_rsDetails = mysql_fetch_assoc($rsDetails);
$totalRows_rsDetails = mysql_num_rows($rsDetails);
mysql_select_db($database_connCosmo, $connCosmo);
$query_rsCategories = "SELECT * FROM categories ORDER BY categoryName ASC";
$rsCategories = mysql_query($query_rsCategories, $connCosmo) or die(mysql_error());
$row_rsCategories = mysql_fetch_assoc($rsCategories);
$totalRows_rsCategories = mysql_num_rows($rsCategories);
?>
Can someone tell me what is going on here?
Kind regards, Ans Hekerman

I can manually type in double brackets, like this:
$varProduct_rsDetails = "1";
if (isset($_GET["productID"])) {
  $varProduct_rsDetails = $_GET["productID"];
this is accepted; no syntax-error report.
I can manually type in single brackets, like this:
$varProduct_rsDetails = "1";
if (isset($_GET['productID'])) {
  $varProduct_rsDetails = $_GET['productID'];
this is also accepted; no syntax-error report.
Dreamweaver itself made this code:
$varProduct_rsDetails = "32";
if (isset($_GET[‘productID’])) {
$varProduct_rsDetails = $_GET[‘productID’];
this was not OK; there was a syntax-error report.
But strange enough, when I do paste this now from here, it is accepted.
So the problem has been, that DW created code that gave a syntax error.
I could repair it by replacing the single qoutes of DW, by typing single quotes in DW manually, or by typing in in DW manually double qoutes!!!
So maybe everybode was right!!!
But is was a very bad problem; maybe a "bug" of the program?
I repeated this about 10 times before I got the solution frome this Forum.
