65,469 PointsTry putting the "++" part before the initialScore. Take a look here:
// Enter your code below
var initialScore = 8
// See how I put the ++ before initialScore? This should fix it :)
++initialScore
let totalScore = initialScore
Hope this helps! ~Alex

// Enter your code below
var initialScore = 8
let totalScore = ++initialScore

65,469 PointsNice catch! I knew you could do that, it's just I like to keep code nice and simple so new programmers wouldn't get frustrated not understanding what's going on.

35,864 PointsAlex,
Just a note, the way he had it should've given the correct result, because the increment will occur regardless if you put the ++ before or after initialScore by the time it's assigned to totalScore since the incrementing is on a separate line.
What you said will make a difference if he put it in one line, like:
let totalScore = initalScore++ \\ <-- this won't increment initialScore before assigning to totalScoreI think it's just a bug in the coding algorithm that's not accepting his original answer, because by the time he assigns totalScore to initialScore, it is already incremented, which should be correct.
