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!

Here is the working code, thanks to alko:

{% load i18n %}

<!-- ... -->

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

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 %}

Had no idea about having to load the tags. Needing to provide a value for count makes total sense. I had to rearrange per below, but works great now -- thanks! – pete Dec 02 '13 at 20:24

To pluralize use this:

Customer{{ forloop.counter|pluralize }}

Probably more what I needed for this simple case of pluralization :) – pete Dec 02 '13 at 20:33

Be aware that this one is not translatable. You probably want to use the blocktrans/plural method. – Matthew Schinckel Nov 29 '15 at 23:41
