Quantity field disappears

I stumbled upon the following issue. I want to display shipping information below the “add to checkout” button in the product information section.

To accomplish this I created “…/customer/addons/my_changes/hooks/products/add_to_cart.override.tpl” This file contains the original code from {hook name=“products:add_to_cart”} where a added a few lines to display information.

However when this hook is used the Quantity field+buttons (+ and -) are no longer displayed on the product information page. This happens even when the hooks is used without my additional code.

Also tried to create a hook one level up “buttons_block.override.tpl”. But this didn't resolve the situation.

Please advice.


When I enter my code to display shipping information directly in “[color=#000000][font=Tahoma][size=3]/skin/basic/customer/common_templates/product_data.tpl” everything works like expected. Not the prefered solution off course but it will do for know.[/size][/font][/color]
