I looked up GET.get Django and found an SO post titled, “Django request.GET <https://stackoverflow.com/questions/3500859/django-request-get>” which has quite a few up votes. Based on that SO answer, In my views.py I changed the line (where I declare the number variable) from `number = request.GET['ccEntry']` to `number = request.GET.get['ccEntry', None]` That gives a different error (a type error this time): https://pastebin.com/L81LVtzi You also mentioned my front end. I had included the template in my original post. I have since refined it so it is more readable. Here is my improved home.html template: <html> <head> <title> Search </title> </head> <body> <center> <form action="{% url 'home' %}"> <div> <h3>Enter your fake Chuckee Cheese Neptune credit card number!</h3> <input type="number" id="number" name="ccEntry" required placeholder=" " pattern=".{16,16}"/> <div class="requirements"> Must be a 16 digit number. </div> <input type="submit" value="Redact!!!"/> </div> </form> <h3>Original Card Number:</h3> {{ number }} <h3>Redacted Card Number:</h3> {{ redacted_num }} <h3> Did this work?</h3> </center> </body> </html> Sam, you also suggested: I think you have made the error of not passing your data to the get header > as you didn't explicitly write this on the form element. I did explicitly include my data in my form element as you can see in the above template. Check the URL and log the get object in Django to make sure the data is > actually appearing in both. The data is present as “ccEntry” in both home.html and in views.py.
