How do I increase a variable in loop by more than one or by another variable?

Question

I'am a first time a programmer and this is really giving me some frustration.  I would really appreciate some help :) . the question is "Create a while loop that will run as long as 'rubies' is less than 'rubyMax'. During each iteration of the loop, increment 'rubies' by 'rubyReward'. When the loop completes, assign a value of true to 'levelFinished'."
```variable_assignment.mm
bool levelFinished;
  int rubies = 0;
int rubyReward = 7;
int rubyMax = 50;
while ( rubies < rubyMax){
  rubies ++ rubyRewards;
}
if ( rubies >= rubyMax){
  levelFinished = true;
}
```

Well first off, you're doing great!  And I know this because if I delete one "s" and change one + to an equals sign, your code passes.  In fact, only one line needs to be altered.  Take a look at how extremely close you are:
You have written:
```swift
rubies ++ rubyRewards;
```
That should be:
```swift
rubies += rubyReward; 
```
Hope this helps!  By the way when we use the += together it will increment the thing on the left side by the value on the right side :sparkles:

Try 
rubies = rubies + rubyRewards;
