Thanks for the great module. This has been very helpful to me.

I ran into one small problem after installation because I hadn't defined "TEXT_SELECT_OPTIONS" in product_info.php along with the other two language definitions in the instructions. I may have missed something, but I believe the instructions step six which currently reads:

6. Modify "includes/languages/english/YOUR_TEMPLATE/product_info.php" by adding...

define('TEXT_OUT_OF_STOCK', 'Out of stock');
define('TEXT_OUT_OF_STOCK_MESSAGE', 'The combination of options you have selected is currently out of stock. Please select another combination.');
should read:

6. Modify "includes/languages/english/YOUR_TEMPLATE/product_info.php" by adding...

define('TEXT_OUT_OF_STOCK', 'Out of stock');
define('TEXT_OUT_OF_STOCK_MESSAGE', 'The combination of options you have selected is currently out of stock. Please select another combination.');
define('TEXT_SELECT_OPTIONS', 'Plese select your product.');
That small change to the installation instructions might save others some time.

Thanks again, this is a great addition to zen cart and greatly improved my store.
