Nutrient value table with NRV calculation

[fm_vlv]

Hi, I'm trying to create a nutrient value table that automatically calculates the nutrient reference values in %. When I add the code, it shows me the following liquid syntax error:

"Expected dotdot but found pipe in "{{ (product.metafields.custom.energie | divided_by: energie_ref | times: 100) | round: 2 }}"

Can anyone make sense of this? Thanks in advance for the help!!

Here's a part of the full code I'm trying to add, just in case this might be useful for troubleshooting:

{% assign energie_ref = 2000 %}


{% if product.metafields.custom.energie %}
      {% assign has_nutrition_info = true %}
      <tr>
        <td>Energie</td>
        <td>{{ product.metafields.custom.energie }} kcal</td>
        <td>{{ (product.metafields.custom.energie | divided_by: energie_ref | times: 100) | round: 2 }}%</td>
      </tr>
    {% endif %}

Hi @fm_vlv 

In Liquid, you don't need to use parentheses to group operations - the filters are applied from left to right.

Please try the following code instead.

{{ product.metafields.custom.energie | divided_by: energie_ref | times: 100 | round: 2 }}

 
or you can even break it down as follows.

{% capture result %}
  {{ product.metafields.custom.energie | divided_by: energie_ref | times: 100 }}
{% endcapture %}
{{ result | round: 2 }}

Let me know if it helps.

Thank you.
