NoReverseMatch: Reverse for 'INSERT URL NAME' not found

I am learning about Django forms and am struggling to render a basic 'results' page for the form.

I would be greatly appreciative if somebody could point out what I'm doing wrong! Thanks in advance :)

ERROR

If your results endpoint is in an app called mapping_twitter, then you can get at it with reverse('mapping_twitter:results').
