It's working but not accepted as correct...

I probably have a syntax error that I'm not seeing. Help?

script.js 
var temperature = 37.5;
Math.round(temperature);
alert(Math.round(temperature));
index.html 
<!DOCTYPE HTML>

It looks like you're using the same function so you're going to get the same result.

Remember that when you use Math.round you're rounding the number up. The second part of the challenge wants you to round the number down. So your challenge should look like this

alert(Math.round(temperature));
alert(Math.floor(temperature));

Good luck :)

Your code looks correct to me! You don't actually need the first part-

Math.round(temperature);

The rest should work fine. Maybe there was just a connection error.

I hope this helps!
