Binary operator error

let area = calculateArea(length, width: width)

var price: Int

switch carpetColor {
    case "gray": price = area * 1
    case "tan": price = area * 2
    case "blue": price = area * 4
default: price = 0
}

return price

}

carpetCostCalculator(length: 10, width: 20)

I get an error on the switch statement that says, "Binary operator " " cannot be applied to operands of type () and Int.

How can I fix this. Thanks

Looks ok to me, except where is carpetColor declared?... but either way it must be something your calculateArea function is returning... could you post that as well?

Thanks Jimi,

I fixed it. You were right, my calculateArea function didn't have a return value.
