Now doesn't working, becuse you don't save Math.round() in the new variable. But the good way here, you put Math.round() into the temperature varible, in the second row use alert() dialog and put inside the variable name. I hope you can solve the second task! :)

Simply pass your rounded temperature to the alert method.

Let me know if this helps here

It is a good solution, but the task doesn't ask for it now. If you don't do what it asks, then you can't go any further, and this is the task 2.

Challenge Task 2 of 2

Open an alert dialog a second time and display the temperature variable rounded downward to the nearest integer. You'll need to check the Mozilla Developer Network to find the proper Math method for this (hint: down is toward the "floor".)

part 1 answer alert(Math.round(temperature));

part 2 answer var temperature = 37.5; alert(Math.round(temperature)); alert(Math.floor(temperature));
