Hey Shak,

So here you want to create a new constant named applePie, and assign it a value associated with the key for apple pie within our dictionary. Let's take a look at this process a step at a time, and start by declaring our applePie constant

let applePie

Now we've got our constant, let's revise how we retrieve a value from our dictionary. We need to the subscript notation on our dictionary, inputting our key for apple pie to retrieve its value. This can be done like so:

iceCream["AP"]

However, in order to complete the challenge, we need to assign this value to our new constant. Bearing the two previous considerations in mind, we can combine them into one statement that will do the job:

let applePie = iceCream["AP"]

Hope that helps, keep it up!
