Thank you for your response.
1. The fact that I'm using a function and then referencing the function in
the
render should not make a difference.
2. I'm not using a database model.
3. Where is the redundancy?
4. When you respond to a request for help an example
of how you would solve the problem whould help, that I is why
I took the time to type in th the forms.py file, the views.py and the
html.
5. You don't need to respond to this.
