TypeError at /courses/PK/edit_quiz/COURSE_ID

This is the error I get when clicking the 'EDIT' button we just created based on 'Edit an Instance' video.

TypeError at /courses/3/edit-quiz/17 quiz_detail() got an unexpected keyword argument 'quiz_pk'

I've been poring over my code and I can't figure out what's throwing this error. Here is the model, URL pattern, and both view functions attributed to this error:

# The edit button block

    {% if user.is_authenticated %}
      <div class="ui divider"></div>
      <a class="ui button" href="{% url 'courses:edit_quiz' course_pk=step.course.pk quiz_pk=step.pk %}">Edit</a>
    {% endif %}

# URL pattern
url(r'(?P<courses_pk>\d+)/edit-quiz/(?P<quiz_pk>\d+)$', views.quiz_detail, name='edit_quiz'),

# Quiz Model
class Quiz(Step):
    total_questions = models.IntegerField(default='4')

    def get_absolute_url(self):
        return reverse('courses:quiz', kwargs={
                       'course_pk': self.course_id,
                       'step_pk': self.id
                       })

    class Meta:
        verbose_name_plural = "Quizzes"

# quiz_detail() view
def quiz_detail(request, course_pk, step_pk):
    course = get_object_or_404(models.Course, pk=course_pk)
    step = get_object_or_404(models.Quiz, course_id=course_pk, pk=step_pk)
    return render(request, 'courses/quiz_detail.html', {
                           'course': course,
                           'step': step,
    })

# quiz_edit() view
@login_required
def quiz_edit(request, course_pk, quiz_pk):
    quiz = get_object_or_404(models.Quiz, pk=quiz_pk, course_id=course_pk)
    form = forms.QuizForm(instance=quiz)
    return render(request, 'courses/quiz_form.html', {
                           'form':form,
                           'course': quiz.course
    })

I called quiz_detail instead of quiz_edit in my urlpattern

url(r'(?P<courses_pk>\d+)/edit-quiz/(?P<quiz_pk>\d+)$', views.quiz_detail, name='edit_quiz'),
