Extra Credit stage: Fizz Buzz - statement expected problem

Question

I just ran into a problem while doing the extra credit stage and I can't figure out how to fix it. The code is as follows:
```Javascript
var Counter = 1;
while(Counter < 100){
    if(Counter % 3);{
        console.log("fizz");
    } //This is where the statement is expected.
else(Counter % 5);{
        console.log("buzz");
    } //This is where the statement is expected.
else (Counter % 3 % 5); {
        console.log("fizzbuzz");
    }
    Counter = Counter - 1;
}
```

Hi @Samuel Lundgren (https://teamtreehouse.com/samuellundgren) 
I'm not sure what the extra credit assignment is asking you to do, but I can see a few mistakes in your code.
Don't add a semicolon after a condition. For example this is wrong: if(Counter % 3);. It should just be if (Counter % 3)
You use the else keyword as the LAST item in a series of conditional statements and it's used to provide a default action if the other conditional statements fail. You don't ever put a condition after else, so else (Counter % 5) is incorrect. You should use else if here which provides another condition for testing:
```javascript
if (Counter % 3) {
} else if (Counter % 5) {
}
```
You have what's called an "infinite loop" here -- that is, the program will NEVER stop. The while condition runs as long as Counter < 100. Since Counter starts with a value of 1 and each time through the loop you subtract 1 from that, Counter will ALWAYS be less than 100 and the program won't end. However, if you wanted the loop to run 100 times, you could do this:
javascript
var counter = 100; 
while (counter > 0) {
  // do stuff
  counter = counter - 1;
}
