Django forms validators- passing in custom validator

I can't get this to pass for some reason when passing in the custom validator?

myproject/forms.py 
from django import forms


class LeadShareForm(forms.Form):
    email = forms.EmailField(validators=[not_treehouse])
    link = forms.URLField()
    honeypot = forms.CharField(widget=forms.HiddenInput, required=False)

    def clean_honeypot(self):
        honey = self.cleaned_data['honeypot']
        if len(honey):
            raise forms.ValidationError('Bad robot!')
        return honey

from django import forms


def not_treehouse(email):
    domain = email.split('@')[1]
    domain = domain.lower()
    if domain == 'teamtreehouse.com':
        raise forms.ValidationError('error')

You're really close!! It looks like you need to put your custom validation method (not_treehouse) above the form class (LeadShareForm). Files are evaluated from top to bottom, so if the not_treehouse method is below the LeadShareForm where it is used, it won't know that it exists yet.
