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.
