the method you're trying to use is parseInt(). Also, I assume it will want you to use the temperature variable, not '37.5'.

Hi Jamondria,

You only need to alert the result of using Math.round(). You also want to use the variable temperature instead of a string value. You can use parseInt() on a string, but since there are no strings needed, you don't need to parse any integers.

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