Cannot assign the value returned by a function to a new constant.

Question

Hi, this is the code I wrote:
---Swift
func getRemainder(value a: Int, divisor b: Int) -> Int {
return(a % b)
}
 let result = getRemainder(10, 3)
---Swift
What am I doing wrong?
Thank you
```functions.swift
// Enter your code below
func getRemainder(value a: Int, divisor b: Int) -> Int {
return(a % b)
}
 let result = getRemainder(10, 3)
```

When you are stuck on challenges it can often be helpful to press the preview button and look at the error message being produced, the errors can often be more helpful than you might expect.
code
swift_lint.swift:13:27: error: missing argument labels 'value:divisor:' in call
 let result = getRemainder(10, 3)
                          ^
                           value:  divisor:

The error comes from the fact that you did not assign labels to the arguments when you called your method, adding the labels that you specified when you created the method like this:
swift
let result = getRemainder(value: 10, divisor: 3)

Will allow your code to pass the challenge.

Hi there, Tatiana!  Oh wow you are soooo close to having this correct!  You set up value and divisor as your external labels.  This means that you have to use them when calling the function, otherwise you'll get a compiler error.  Take a look at how close you really are:
```swift
 let result = getRemainder(value: 10,  divisor: 3)
```
Hope this helps! :sparkles:
