Hi John,

The reason is you need define the variable "answer" as an empty string. If you don't, you'll get an error saying "undefined local variable or method 'answer' ".

Hope that helps!

Hi, you need this variable before the loop to solve scope variable problems. If you define the variable answer inside the loop you could use the variable inside of code of block of while loop but you could not use it as part of the condition of the loop.
