    DavidO map only works on properties and the property name should be where you have 'capitalize' in teh code. 'capitalize' is not a property of any item in your array, that's why this won't work. 

    Try this:

    {% assign fullName = "tony peter" %}
{% assign names = fullName | split: ' '  %}
{%- capture capitalizedNames -%}
  {%- for name in names %}{{ name | capitalize }} {% endfor -%}
{%- endcapture -%}
{{ capitalizedNames }}

    Thanks Arso 🙏🏻

    I did see some comments about properties in the Shopify docs and that makes more sense now. Back to the for loop, but good to know it wasn't just me. 😂 Thanks for the code suggestion too.
