Have you verified that 'member' and 'input' are populated with values when the form is submitted? You should be able to put print() statements at various points in your code and watch the output on the dev server console. You should also check that the 'a' variable is populated just before it is placed into the context. 

Also, be careful using input as a variable name. That clashes with the input() function in Python 3.
