Thank you for your reply, but I don't really understand how am i able to make it to the page I want, does it mean I need to write a new function in view and pass in the retrieved answer from user, then do the redirection/ rendering? Could you give me some hints about how the syntax would be, because I am a total newbie in Django and couldn't find much resources about my situation. Thank you!
