Stuck with math.round and math.floor in Javascript, could you guys help me please?

Hi guys! I'm a bit stuck with this task, could you help me? :)

Question: For this Code Challenge you need to use JavaScript's Math methods. Open an alert dialog and display the temperature variable rounded to the nearest integer.

My answer: var temperature = 37.5; alert(Math.floor(temperature));

In the preview it works like a charm. However, when I click "Check work" it says: Bummer: Did you use the Math.round() method?
No, I did not, cause the task was to use the floor one. If I change my script to "Math.round" like the error message suggested, it now says: Bummer: Did you use the Math.floor() method?

So what am I supposed to do now? What's the real problem here?

Thanks a lot for the answer!

script.js 
var temperature = 37.5;
alert(Math.round(temperature));

The first task says "display the temperature variable rounded to the nearest integer", so you need to use Math.round(), not Math.floor(). For the second task, you need to add another alert() method below that using Math.floor(). Sounds like maybe you replaced the first method instead of adding another one.
