I have a problem with the first question involving math methods in the javascript basics course.

I have to use the alert() function, but when i did i get an error message that says variable alert is undefined. This is the code i used: var temperature = Math.round(37.5); Alert(temperature);

I'm not sure where i went wrong.

script.js 
var temperature = Math.round(37.5);
Alert(temperature);

It's a typo or misspelling.

JavaScript is case sensitive, and instead of the function name "alert" (with a lower-case "a"), you wrote "Alert" (with a capital "A").
