Thanks for your help!")* Hi, Why display the custom field via a module ? Can't you create a custom field of the table "item" via the Display>Custom fields menu and use the display options to just have HikaShop display it before the add to cart button for you ? Why is that not possible ? Where does this "external stock quantity" comes from ? Why do you want to add it to the product page ? What is its purpose ? If you can provide more explanation on what you're trying to achieve, we should be able to tell you what to do.

Thanks for your help!")* Ok, I'll try to explain ![:)](/media/kunena/emoticons/8.png ":)") I would like to create an interface similar to the current shopping cart block, where the quantity of an external stock would be displayed. If the visitor doesn't have the right quantity in the internal stock, he could use the external stock control to select the extra quantity that suits him and I would send this in an email to the email address set in the admin interface (e.g. using rsform). So the basic add to cart button would do the usual hikashop procedure, while the second block would do the external warehouse enquiry. Visitor selects a quantity, adds to list, goes to next product, adds to list. Then at the end he sends this information (e.g. by clicking on a button in a modal) and I can contact him based on this We have a lot of types of products, few in internal stock, more in external stock.

Thanks for the details. I think it's a good idea to add your interface to the product details page to handle that. Adding it in product / show_default can probably be done. One thing you need to be wary off is that the whole product / show_default is inside form tags from the product / show view file. And in HTML, you can't have a form element inside another form element. That's invalid, and it will create erratic problems with the forms. So you might have to move the ending tag of the form from product / show to product / show_default as to encompass the default quantity area of HikaShop, without encompassing your own form. Also, you can directly put your custom form inside product / show_default. You don't have to create module with your code inside and insert it in the view with another extension. That should simplify work for you. Finally, if you have an error when you add the tag from modules anywhere in product / show_default, it probably means that you've added it at the wrong place in the code.

Thanks for your help!")* Hi, If you want to have your javascript code triggered when the currently selected variant is changed, you can use the event system of HikaShop and register for hkContentChanged: [ www.hikashop.com/support/documentation/6...tml#hkContentChanged](https://www.hikashop.com/support/documentation/62-hikashop-developer-documentation.html#hkContentChanged) The full product name, with the main product name + the variant name will be in the div with the id hikashop_product_name_main So you can directly take it from there without any processing. Something like this: Code: let productNameMain = document.querySelector("#hikashop_product_name_main").innerHTML; For example: Code: if(window.Oby) { window.Oby.registerAjax(["cart.updated","wishlist.updated"],function(params){ let productNameMain = document.querySelector("#hikashop_product_name_main").innerHTML; document.getElementById('variant-name-display').innerHTML = productNameMain; }); } The following user(s) said Thank You: [mizso676](/forum/user/82243-mizso676 "View mizso676's Profile") Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtL2NvbnRlbnQtY3JlYXRpb24vOTA5MjUzLWN1c3RvbS1maWVsZC1pbi1jdXN0b20tbW9kdWxlP3RtcGw9bWFya2Rvd24=) or [Create an account](/component/users/registration?Itemid=101) to join the conversation.
