//Dafault Values
func carpetCostHaving(length: Int, width: Int, carpetColor color: String = "tan") -> Int { //Gray carpet - $1/sq ft //tan carpet - $2/sq ft //Deep Blue Carpet - $4/sq ft
let areaOfRoom = area(length: length,width: width)
var price = 0
switch color {
case "gray": price = areaOfRoom * 1
case "tan": price = areaOfRoom * 2
case "blue": price = areaOfRoom * 3
default: price = 0
}
return price
}

your calling the area function but I dont see it defined in your code.
If memory serves me it should look something like this:
//Dafault Values
func area(length: Int, width: Int) -> Int {
return length * width
}
func carpetCostHaving(length: Int, width: Int, carpetColor color: String = "tan") -> Int { //Gray carpet - $1/sq ft //tan carpet - $2/sq ft //Deep Blue Carpet - $4/sq ft
let areaOfRoom = area(length: length, width: width)
var price = 0
switch color {
case "gray":
price = areaOfRoom * 1
case "tan":
price = areaOfRoom * 2
case "blue":
price = areaOfRoom * 3
default: price = 0
}
return price
}
carpetCostHaving(length: 10, width: 15, carpetColor: "tan")
// returns 300
I hope this helps
