Okay, so I am working on a weather application, and I wrote the following test code to verify that the user entered a valid state abbreviation:

var input = prompt("What state are you in?");
var lower = input.toLowerCase();
var categories = [ 
    "ma", 
    "ny", 
    "ct", 
    "ri", 
],
var found = $.inArray(lower, categories);
if (found > -1) {
    alert("Cool!");
    }
else {
    alert("Oh no!");
    }

But for some reason, it doesn't work.

Take a look: /

Does anyone know why this is? I probably just made a silly mistake, but any help would be greatly appreciated.

Check your console window in your browser, press F12, there are errors.

The ma after ] should be a semi-colon:

var input = prompt("What state are you in?");
var lower = input.toLowerCase();
var categories = [ 
    "ma", 
    "ny", 
    "ct", 
    "ri"
];
var found = $.inArray(lower, categories);
if (found > -1) {
    alert("Cool!");
    }
else {
    alert("Oh no!");
    }
