Django {% blocktrans %}: How to handle pluralization inside a for loop?

Question

I have the following loop in my Django template:

{% for item in state.list %}

    <div> HTML (CUSTOMERS BY STATE) </div>

    <!-- print sum of customers at bottom of list -->
    {% if forloop.last %}
        <h4>{{ forloop.counter }} Valued Customers</h4>
    {% endif %}

{% endfor %}

Obviously, if I end up with only one customer, I'd like to print singular "Valued Customer"

According to Django's docs, one should use blocktrans. Tried the following, a few flavors of nesting:

    {% blocktrans count %}
        {% if forloop.last %}
            <h4>
                {{ forloop.counter }}
                &nbsp;Valued Customer
                {% plural %}
                &nbsp;Valued Customers
            </h4>
        {% endif %}
    {% endblocktrans %} 

Keep getting TemplateSyntaxError: Invalid block tag: 'blocktrans', expected 'empty' or 'endfor'

Is there no way to combine with another loop? Any ideas how to solve? Thanks!

Probably, you forgot to load translation tags. Add following line at the top of your template:

{% load i18n %}

After you fix that, note that for a blocktrans tag after count a variable, whose value will serve for plural detection, should be specified, so you probably need something like

{% blocktrans count count=forloop.counter %}
