# --description--

When a function or method doesn't take any arguments, you may forget to include the (empty) opening and closing parentheses when calling it. Often times the result of a function call is saved in a variable for other use in your code. This error can be detected by logging variable values (or their types) to the console and seeing that one is set to a function reference, instead of the expected value the function returns.

The variables in the following example are different:

```js
function myFunction() {
  return "You rock!";
}
let varOne = myFunction; // set to equal a function
let varTwo = myFunction(); // set to equal the string "You rock!"
```

# --instructions--

Fix the code so the variable `result` is set to the value returned from calling the function `getNine`.

# --hints--

Your code should fix the variable `result` so it is set to the number that the function `getNine` returns.

```js
assert(result == 9);
```

Your code should call the `getNine` function.

```js
assert(code.match(/getNine\(\)/g).length == 2);
```

# --seed--

## --seed-contents--

```js
function getNine() {
  let x = 6;
  let y = 3;
  return x + y;
}

let result = getNine;
console.log(result);
```

# --solutions--

```js
function getNine() {
 let x = 6;
 let y = 3;
 return x + y;
}

let result = getNine();
console.log(result);
```
