7. You Deserve it!

I keep getting NaN as a result im assuming something is misnamed or my math is off but im not sure how

Replace this line with your code.

here:

cashRegister.applyStaffDiscount("me");

you supply "me" is argument. But a string doesn't have discountPercent property. Supply the me instance as argument

Wow I just spent three days thinking i totally sucked at this and i was the worst coder in the world and the whole time it was a couple quotation marks. Lol Thank you very much i guess i need to get better at the details

Thank you

those quotation marks make a huge difference (string vs variable, in this case the variable is object instance)

Programming really requires attention to detail, it will get better
