I can't get this to work with the Book Type add-on. The back-in-stock notification option does not show on the product page if the product type does not equal 1.


Any help you could provide would be VERY appreciated!


I'm assuming it's tied to the product type after I tried the following:

Checked against 2 items: A with product-type = 1, and B with product-type = 7

Copied tpl_product_info_display.php from download as tpl_product_info_display.php and tpl_product_book_info_display.php (so the files were identical)

Checked both items - same display template, just a different value in the product-type field

A (with product-type 1) shows option correctly, B does not show option at all

Both are using the EXACT same product_info_display template. I didn't modify any of the other files at all.
