# Problems for loop ObjC

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)

When I run the task, it said me like that: Bummer! Better check your syntax!

This is my code:

int mathTotal; bool isComplete;

for(int i = 5; i <= 25; i++){ mathTotal++; if(i == 25){ isComplete = true; } }

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

for(int i = 5; i <= 25; i++){
mathTotal++;
if(i == 25){
isComplete = true;
}
}
```

Hi Francisco,

You're very close - the only piece you're not quite doing correctly is the instruction "In each iteration, add the incrementing value to mathTotal". The incrementing value is i, so you need to add the value of i to mathTotal, rather than simply incrementing. You only need to change one line of your code to pass the challenge:

``` int mathTotal;
bool isComplete;

for(int i = 5; i <= 25; i++){
mathTotal = mathTotal + i;  // Here's the change
if(i == 25){
isComplete = true;
}
}
```

Hi!! Thanks, I don't understand the question correctly.
