Hi @petertphillips Welcome to shopify community. Can you share the code you added pls? Which theme are you using?

we have the venture theme and the code for the snippet is : {% if product.available %} Add to cart {% else %} Backorder (Usually ships within 48 hours) {% endif %} and then added in to the code on page is {% render ‘backorder-button’ %}

OK, Can you explain more detail to me when and where the error “Required parameter missing or invalid: items” shows

I think it is possible. Replace your current code with below cope snippet. Feel free to reach out if you need any further assistance

sadly same issue with missing parameter

Hi @petertphillips

Do you allow sell product that out of stock?
