33,366 PointsYou are almost there! What you need is to tell your program what 'number' you are adding to the sum. Remember that you can access a value inside an array by using the index. See the following code for an example:
var array = [1, 2, 3]
/*accessing the first number. - remember that when we count the index, we start from 0*/
let firstIndex = array[0]
If this doesn't make sense to you, just let me know, then I can give you another hint :)
