**Tell us what’s happening:**

Hi. I’m having a hard time with this problem. I feel like the code should execute and have been stuck on this all day. Any ideas where I’m going south?

**Your code so far**

```
// Setup
function abTest(a, b) {
// Only change code below this line
if (a < 0 || b || 0) {
return undefined;
}
// Only change code above this line
return Math.round(Math.pow(Math.sqrt(a) + Math.sqrt(b), 2));
}
// Change values below to test your code
abTest(2,2);
```
