Number of items stock not visible on the product update page in the adminstration section

Hello
Tutorial "Inventory management administration II" created by Kate Ford

My problem is that i can't see the numbers of items in stock on the products update page

In the section "Edit product update page"

6. To begin creating the counter, copy the following snippet of code (Ctrl or Cmd +C):
<?php echo $row_ADAproducts[‘RemainingInventory’] ?>

I suppose that this must be <?php echo $row_WADAproducts[‘RemainingInventory’] ?> instead of ADAproducts, tell me if i am wrong.

But still no numbers of items in stock are visible

Can you help me to see what i am doing wrong in my codes, the two file pages are in attachment

Otherwise it's a very good tutorial

Thanks for cooperation
