A client did not want to show the number in inventory, but wanted to keep track of inventory.

The product availability showed and they wanted it removed.
Here’s the process (simple once you read this – time consuming if you go to the forums).
The code that displays the product availability is in your fly_page file.
Where did they ever come up with that term?  …for another post.
Find out what fly page you are using in the categeory.
The one used in the clien’t site was:
Flypage_Images
public_html/components/com_virtuemart/themes/default/templates/product_details/flypage_images.tpl.php
WOW – quite a directory / code structure!
On about line 56 there is a line:
echo $product_availability;
Delete it.
Done.
