reverse-text-filter

I am stuck on https://teamtreehouse.com/library/customizing-django-templates/building-custom-filters/reverse-text-filter

I have entered :

from django import template

register = template.Library()

def reverse_text(text):
    my_string = "balloon"
    text = my_string[::-1]

    return text

Which I believe to be correct but I am getting:

Bummer! The reverse_text function isn't returning the string we expected. Try this: text_to_reverse[::-1])

What am I missing?

It doesn't want you to make your own variable for the string. This will be provided as the argument for your 'text' parameter. You pretty much had it right, you just needed to use the argument that is passed to the function and return the reverse of that argument. Here is the code:

from django import template

register = template.Library()

def reverse_text(string_argument):
    return string_argument[::-1]
