Return Early Pattern for Functions still no working

Tell us what’s happening:

Im confused how to move onto the second return.

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

Link to the challenge:

Why do you have that semi-colon before the { in your if statement?

That fixed it, thanks!
