Not sure what I am doing wrong with the optional binding quiz.

Hey Erik Huang,

This was a tough one for me to follow as well. Let me see if I can help. The problem I can see is in your second let statement. You can't pass both a key of "cast" and an index of 0 in for this statement. You have to break them up.

Using the movie constant you created with the first if let statement, you want to access the value associated with the "cast" key, which is an array of Strings. You assign the value you receive from this key, the array, to another constant - I will use the constant actors in my example below - and THEN you can access the first item in the array using the index.

let movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "Léa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]
​
var leadActor: String = ""
​
// Enter code below
​
if let movie = movieDictionary["Spectre"],
    let actors = movie["cast"] {
        leadActor += actors[0]
    }

I think my explanation was a bit rough so let me know if I need to clarify this for you. It's easier to see what's going on just by looking at the code.

Good Luck!
