Not sure which part is wrong

Question

I'm a little hungover but please help :D
```structs.swift
struct Person {
    let firstName: String
    let lastName: String
func getFullName(firstName a: String , lastName b: String) -> String {
return \(firstName) + " " + \(lastName)
}
}
```

Your formatting for the return string statement is incorrect. There are two ways to use variables with Strings:

1. **String interpolation**:

This is when you get the value of a variable using "\(variableName)" When you do this, you interpolate within the string itself, meaning your desired return statement would be:

return "\(firstName) \(lastName)"

2. Concatenation:

This is when you add together, say two variable strings, to get a new combined string. Using concatenation, your return statement would be:

return firstName + " " + lastName;

you can read more about working with Strings in Swift here (https://developer.apple.com/library/ios/documentation/Swift/Conceptual/Swift_Programming_Language/StringsAndCharacters.html)
