Try this: alert ( Math.round( temperature ));

alert ( Math.round( temperature ) );

Hi Chuck,

Sanjay gave the right answer, but just to help out a bit more, the reason your initial solution was not working is because your parenthesis was facing the wrong direction after Math.round. Your initial solution was:

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

As you can see, it is facing the opposite direction. Below is the corrected solution, you should also use a semicolon following your temperature variable declaration.

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

Looks like there is an issue with the code pasted above. There is a opening bracket ( missing around the variable temperature. This should work 

alert(Math.round(temperature));

Multiple statements on the same line need to be separated by semicolons. You're missing one after 37.5. Also, the parenthesis after Math.round is facing the wrong direction.
