{
    isComplete = YES;
}

Hi Rich,

The challenge is to add up the numbers from 5 to 25 using the for loop, storing that total in the mathTotal variable you've created.

Once that's done, then set the isComplete boolean to YES. Your loop is spot on but inside it, you aren't adding i to mathTotal. Plus, you're setting isComplete to YES before i reaches 25.

Something like this should work:

int mathTotal; // We should probably initialize this
bool isComplete;

for (int i = 5; i < 26; i++){  // or <= 25
  mathTotal += i;
}

isComplete = YES;

I hope that makes sense.

Steve.
