Hello, I am having trouble finding out what my error is. I need to find out how to add the external name.

Really close. You just reversed the internal and external names:

func getRemainder(value a: Int, divisor b: Int) -> Int {
    return a % b
} 

let result = getRemainder(value: 10, divisor: 3)
