Could not parse the remainder

Inside a {% %} tag, variables aren't surrounded by {{. Try this:

{% ifequal num buildSummary_list.number %}

Also, it looks like your two comparisons can be joined with an else:

{% for num in buildSummary_list.paginator.page_range %}
    {% ifequal num buildSummary_list.number %}
        <b>{{num}}</b>
    {% else %}
        <a href="?page={{num}}"><b>{{num}}</b></a>
    {% endifequal %}
{% endfor %}

I got this error when I forgot the '' around the path to a static file

This gave the error:

 <link rel='stylesheet' href="{% static css/style.css %}">

This fixed the error:

 <link rel='stylesheet' href="{% static 'css/style.css' %}">
