I realized that it wouldnt work unless I deleted the code that was read from the previous test: arrayOfInts 
Not sure why it malfunctioned just because i had the answer to the previous challenge included
var arrayOfInts: [Int] = [1, 2, 3, 4, 5, 6] arrayOfInts.append(7) arrayOfInts = arrayOfInts +  let value = arrayOfInts

What's the issue exactly? This code passes Challenges 1 through 3, and Challenge 4 doesn't seem like there's any attempt there yet.
