The last line you've got it kind of backwards altough it might work like Catalin said. you said this:

var profit=wholeSale*quantity-salesTotal;

but the proper Math syntax is:

var profit = salesTotal - (wholesalePrice * quantity);

the code in the "()" makes it run first as the syntax will aknowledge that it should be used first and then use the first variable called salesTotal.

if I were you I'd check the videos one more time on the syntax of math in Javascript, if you don't learn the correct syntax in time, it will get really tricky in the end :)

On the first line you declare a variable 'wholesalePrice', but on last line you used 'wholeSale'. I think that is the problem.
