JavaScript JavaScript Basics (Retired) Making Decisions with Conditional Statements Using Comparison Operators

I don't understand why my code ain't working!

i have added the if and else statement but i don't know why it's not working.

script.js
var a = 10;
var b = 20;
var c = 30;

if(a > b) {
    alert('a is GREATER than b!');
} else {
    alert('a is NOT greater than b!');
}

As Dave pointed out, the challenges can be very picky about strings they give you. Be sure to always code sample outputs exactly as in the instructions. I recommend cut-and-paste to avoid typos.
