Add to cart button not working

Hi,

We're having a serious issue with the business edition on the button that is added to the article. The button renders perfectly but links to the homepage of the site.
The product doesn't have any special or custom fields applied - it's a simple product with price rendered through:

{product}13|name|cart|pricedis3|pricetax1{/product}

This is the link that is rendered in the add to cart button:

<a class="hikashop_cart_button" href="/" onclick="var field=document.getElementById('hikashop_product_quantity_field_1');return hikashopModifyQuantity('13',field,1,0,'cart',0)">Add to cart</a>

Thanks for any help

Hi Nicolas,
Thanks for the reply. The issue happened if the cart button was added inside a nested div in article. Placing it in a clean area the button works.
Thanks
