Are you on step 1?

It looks like you're currently looping through "while counter <= sum". This is heading towards the right direction, however the instructions want you to loop as long as "counter" is less than the number of items in the array, not the sum.

They also give a hint to use the count property, which counts up the number of items in your array. We use the count property by typing the name of the array and calling its count with dot notation.

let exampleArray = [3, 4, 26, 7, 99]

exampleArray.count
// this would give a count of 5

Once you have your while loop set, you then need to give it code within its body that will keep it from looping forever, since currently "counter" is set to zero, and nothing is changing that. I recommend re-watching the While and While Repeat video, this issue is discussed about 1 minute in.

Hope this helps!
