Hi Benoit, you're enclosing the Math.round() function and the 'temperature' variable in double quote marks thereby turning it to an ordinary string and you typed a comma in between both of them which is a syntax error.

 alert (" Math.round(),temperature");

You apply the Math.round() method by enclosing the number, variable or value (you want to approximate) in its parenthesis.

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