Not working please some help

```
// Enter your code below
func getRemainder(a value: Int, b divisor: Int) -> Int {
let operation = a % b
return operation
}

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

*a* and *b* are the external names for the variable. *value* and *divisor* are the names for the variable in the function.
eg.. when you call the function you would do the following:

`getRemainder(a: 5, b: 10)`

hence a and b here are used externally from the function

In the function:
`let operation = value % divisor`

value and divisor are used.

So in the function you will use value instead of a and divisor instead of b.

value and divisor are just names for the same variable to make the code more readable.

###### James Vlok

17,059 Points```
func getRemainder(value a: Int, divisor b: Int) -> Int{
return a % b
}
```

This should work. the question states that the external variable names need to be *value* and *divisor*.
In the function definition just swap *value* and *a* , *divisor* and *b*

Sorry didn't see that it was apart of a code challenge.

All the best
