Soy bastante nuevo en los formularios en django.

Mi problema es que tengo algunos modelos muy grandes que tengo que dividir en una serie de formularios más pequeños para que los usuarios completen.

Así que he estado jugando con formas crujientes y ayer, después de ver el tutorial de Mike Hibberts (tutorial 19 de Python Django - Uso del asistente de formularios) en YouTube, quería ver si podía hacer que esto funcionara con una forma crujiente.

Todo parece estar bien para mí, sin embargo, cuando presiono enviar, el formulario parece estar validado pero no continúa con el paso 2.

¿Estoy haciendo esto completamente mal?

¡Gracias por cualquier ayuda o sugerencia!
