Replace the word "is" in the sentence in the template with your custom template tag. Don't forget to pass in the num_elf

please help me out I am not able to pass this challenge

code_challenges/templatetags/fairy_extras.py 
from django import template

register = template.Library()

@register.simple_tag
def conjugate_is(num):
    if num==1:
        return 'is'
    else:
        return 'are'
code_challenges/templates/code_challenges/list.html 
{% load fairy_extras %}

There {{ num_elf | conjugate_is }} {{ num_elf }} el{{ num_elf|pluralize:"f,ves" }}.

Hi Pabba,

I struggled on this as well. Because it is a simple_tag it should be placed between {% %} not {{ }}.

{% load fairy_extras %}

There {% conjugate_is num_elf %} {{ num_elf }} el{{ num_elf|pluralize:"f,ves" }}.

Check out the django docs here for more info: https://docs.djangoproject.com/en/1.11/howto/custom-template-tags/
