I am unable to complete 'Doing Math' Challenge.

For some reason I am unable to move ahead in 'Doing Math' code challenge of Javascript Basics's Number subsection. For task 1, I have added the following statement : var salesTotal = retailPrice * quantity; As directed by the instructions, moving on to complete task 2 requires addition of the following statement : var profit = salesTotal - (wholeSalePrice * quantity); according to instructions specified in the task. On clicking check work I receive a prompt Oops! It looks like Task1 is no longer complete. Please suggest what's the issue as I am done with the amount of thinking I could to resolve this?

script.js 
var wholesalePrice = 5.45;
var retailPrice = 9.99;
var quantity = 47;
var salesTotal = retailPrice * quantity;
var profit = salesTotal - (wholeSalePrice * quantity);

Seems like you have a typo on wholeSalePrice.

There's a lower case "s" in the variable declaration but an upper case "S" in the multiplication.

JavaScript is case sensitive.

Your variable has a lowercase S in 'wholesalePrice'

Later on in the code you call the variable but with a capital S 'wholeSalePrice'

Maybe this is causing your error.

Hope this helps!
