FizzBuzz Function Error

Hi everyone, I wanted to take the FizzBuzz exercise in Swift a step further and make it into a function where you can select the range of numbers that the are getting "FizzBuzzed." I'm having a problem with it. I'm getting an error that says:

"ERROR at line 25, col 11: missing argument label 'high:' in call fizzBuzzer(100,150) ^ high: "

Here is my code. I'd really like to know what is going wrong with it so any help is appreciated. I'm assuming it's a simple fix and I've just missed something. Thanks

let fizz = "Fizz"
let buzz = "Buzz"

func fizzBuzzer(low: Int, high: Int) {
    let counter = low...high

    for count in counter {
        switch count {
            case count where count % 3 == 0 && count % 5 == 0:
                print("\(count) makes \(fizz+buzz)")
            case count where count % 3 == 0:
                print("\(count) makes \(fizz)")
            case count where count % 5 == 0:
                print("\(count) makes \(buzz)")

Hey Jordan,

You are missing the second external variable name in your function call. If you put

fizzBuzzer(100, high: 150)

your code will execute with no errors. I could go into a very long explanation, but I would mostly be quoting the Apple Dev Docs. So, if you want, you can read up on functions and function calls at your leisure.

But, other than that... nice code. :)
