Don't understand quiz answer

The quiz question asks me to assign a constant and retrieve the 5th number from the array. The code i've entered does this. What am I doing wrong?

arrays.swift 
// Enter your code below

var arrayOfInts = [100,200,300,400,500,600]

arrayOfInts.append(700)

arrayOfInts += [800]

let numberFive = arrayOfInts[4]

where you have 

let numberFive = arrayOfInts[4]

they just wanted it to be named value. Everything else is correct

Correct code would just be

let value = arrayOfInts[4]

ok thx.

it would be so helpful if you could reveal answers on quizzes. It really stops the learning when the question / answer subtleties are so minimal.
