Module 1, Lesson 9 Challenge

Hihi all. After running the Level 9 Challenge, I found an issue of my code. It mentions Can not fine “income” in scope.

When I check the answer when comparing to mine, there is a “_” for argument label. Is it necessary ?

I think I need to support about this.

Hi Avery,

Welcome to the community

The error is that the parameter for totalWithTax is a double named income and what you need to pass to it is the value in subtotal like this:

let eachPerson = new.totalWithTax(income: subtotal)

The rest of your code is fine.
