A few things I notice here. I would double-check the variable name that you're declaring. It should be "tempRounded". As well, you're using Math.floor method which returns the largest integer less than or equal to x. I would try using Math.round which returns the value of the number x rounded to the nearest integer. Finally, don't forget to end with a semi-colon.

Let me know if you're still having the same issue.

const temperature = 37.5;

var tempRounded = Math.round(temperature);

var tempRoundDown = Math.floor(temperature);
