Dear @yara
Jinja is somehow not supporting value outside the loop. I dont know is this the correct way … but it solves our problem.


 {% set grand_total =namespace(total=0) %}

{% for row in doc.items %}
{% set row_total = (row.qty|float) * (row.cost_for_print|float) %}

{% set grand_total.total = grand_total.total + row_total %}
{% endfor %}

Merchandise Total: {{ grand_total.total }}
