Django passing view url variables inside a template

I feel like this is going to be an embarrassing question but I can't find the answer I've tried google but I am getting fairly frustrated so I just decided to ask here. I've got this code snippet inside a template file in django

{% url cal.views.month year month "next" %}

I run the code and get this error Reverse for 'courseCalendar.views.month' with arguments '(2013, 9, u'next')' not found

Why is it that when I try to pass variables in a string it puts the u in there as well. This is very frustrating and I would really appreciate someones two cents.

Edit: Everything works fine if I don't include the string "next" and use a variable instead like the year and month variables so it's not a url problem or template problem.

url pattern

from django.conf.urls import patterns, include, url
urlpatterns = patterns('',
    url(r'', 'courseCalendar.views.main'),
    url(r'^month/(?P<year>\d{4})/(?P<month>\d{2})/(?P<change>[a-z])/$', 'courseCalendar.views.month', name="month"),

)

Views

Change to the following:

In your view file:

def month(request, year=1, month=1, change="None"):

In your url file: 

url(r'^month/(?P<year>\d{4})/(?P<month>\d{2})/(?P<change>\w+)/$', 'courseCalendar.views.month', name="month"),

After you change to the above, post here the error message if you're receiving an error.
