I need to add my custom customer metadata to the address section on my packing slip. I have been using the following code:
{% assign customer.metafields.adv_reg.LICENSE = nil %}
{% if customer.metafields.adv_reg.LICENSE %}
{{ customer.metafields.adv_reg.LICENSE }}
{% endif %}
{% if customer.metafields.adv_reg.LICENSE != blank %}
{{ customer.metafields.adv_reg.LICENSE }}
{% endif %}
