Reverse for 'guestbook.posts' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

Question

I keep getting this error and I've spent hours trying to figure out what is wrong with my code.

Here are my files:

views.py

from django.shortcuts import render
from django.http import HttpResponse
from django.template import RequestContext, loader
from django.utils import timezone

from guestbook.models import Post

# Create your views here.
def posts(request):
    if (request.POST.get('name', 0)):
        name = request.POST['name']
        text = request.POST['text']
        title = request.POST['titile']
        p = Post(name=name, title=title, text=text, pub_date=timezone.now())
        p.save()
    newest = Post.objects.order_by('-pub_date')[:5]
    template = loader.get_template('guestbook/index.html')
    context = RequestContext(request, {
        'newest_post': newest,
        'kalli': 543
    })
    return HttpResponse(template.render(context))

def write(request):
    return render(request, 'guestbook/form.html')

urls.py:

from django.conf.urls import patterns, url, include

from guestbook import views

urlpatterns = patterns('',
        url(r'^$', views.posts, name='posts'),
        url(r'^write', views.write, name='writer'),
)

*/urls.py

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls', namespace="polls")),
    url(r'^guestbook/', include('guestbook.urls', namespace="guestbook")),
    url(r'^admin/', include(admin.site.urls)),
)

My error is somewhere in this file, But I put in other codes in the question just in case,

NoReverseMatch at /guestbook/write

The above is my Error.

To reverse namespaced URLs, you'll need to refer to them as guestbook:posts rather than guestbook.posts, per the documentation.
