reponses file inconsistent variable name

[paulorvdc]

tried to run it today before looking into creating tests tomorrow and found a simple mistake with a variable named differently from the click command.
also fixed another problem I created because I changed how I wanted to declare the output file to be consistent with the ask command and forgot part of the old code.
