# What am I missing that the quiz is explicitly asking for?

The question is:

"Create a for loop that will begin with a value of 5 and end with a value of 25. In each iteration, add the incrementing value to mathTotal. When the loop has finished running, set 'isComplete' to true. (HINT: the last value used INSIDE the loop should be 25)"

In Xcode I included NSLog for both the bool and the final value. The results of the code are as follows:

2016-10-10 21:39:05.331284 Test[1929:72178] The problem is complete. 2016-10-10 21:39:05.332439 Test[1929:72178] 25

This quiz still gives me a "Bummer! Better check your syntax!" error. If there was a syntax error, Xcode would yell at me and tell me, however this isn't the case. The only alert I got was that mathTotal might not be initialized (since I left it null), so I simply changed it to 0 - however I get the error regardless on the website regardless of mathTotal's time of initialization.

variable_assignment.mm
```    int mathTotal = 0;
bool isComplete;

for(int i = 5; i <= 25; i++){

mathTotal = i;

if(mathTotal == 25){
isComplete = true;
}
else{

isComplete = false;
}
}
```

I've even adjusted the code that runs in Xcode (have tried this as well):

```int mathTotal;
bool isComplete;
int goalMathTotal = 25;

for(int i = 5; i < 26; i++){

mathTotal = i;

if(mathTotal == goalMathTotal){
isComplete = true;
NSLog(@"The problem is complete.");
}
else{

isComplete = false;
}
}

NSLog(@"%i", mathTotal);
```

and the site still says there is a syntax error. I'm really confused, both pass 25 through the loop, and when the loop is complete set the value of isComplete to true :(

Hey Matthew,

A bit simpler than you might think, just a few things:

• In each loop 'increment' the amount
• at the end of the loop set '`isComplete`' to true
```int mathTotal = 0;
bool isComplete;
for (int i=5; i<=25; i++) {
mathTotal += i;
}
isComplete = true;
```
