Not sure why I am getting the error?

Since you have the amazon_soup used as an argument to the method and you use it as a variable which is undefined.

It should be:

print(getnextpage(geturl(amazon_url)))

The amazon_soup variable you have declared is local to the method geturl.

The variable "amazon_soup" is not defined in the current context. In python, and in many other languages, the "level", in which you define a variable matters. This means that you cannot access it from outside of the "level" you are in. In your case, the variable is defined in a function and thus it cannot be access outside of this function. Change the code in line 4 to define amazon_soup at the start, the same way you did for amazon_url. So just add

amazon_soup = None

at the start of line 4. Then run line 4 and line 5.
