Hi guys,

This is for the Order Confirmation email (Shopify). 

My goal is to use the FOR loop and loop through all the items in the order and check item.variant_title. 

- If at least one variant_title has any of the following words: 'ebook', 'e-book' etc - display message A. 

- If none of variant_titles has any of those words, display message B.  

Important: this has to display only one message - A or B, no matter how many items are in the order. But NOT one message per every line item. So that's why I am using the "with" operator here and the if/else conditions. 

The code looks fine, but Klaviyo gives an error, maybe something is not supported?

Thanks!

{% with contains_physical_book = False %}
  {% for item in event.extra.line_items %}
    {% if 'e-book' not in item.variant_title|lower and 'ebook' not in item.variant_title|lower and 'audiobook' not in item.variant_title|lower and 'audio book' not in item.variant_title|lower %}
      {% with contains_physical_book = True %}
      {% endwith %}
    {% endif %}
  {% endfor %}

  {% if contains_physical_book %}
    Message A
  {% else %}
    Message B
  {% endif %}
{% endwith %}
