Using cookies, I want it to remember the colour layout of the page. (So, if they set the gallery one color and the body background another color, it will save that on refresh. But it doesn't seem to be working.

jQuery:

$(document).ready(function() {

    if (verifier == 1) {
        $('body').css('background', $.cookie('test_cookie'));
    }

    if (verifier == 2) {
        $('#gallery').css('background', $.cookie('test_cookie'));
    }

    if (verifier == 3) {
        $('body').css('background', $.cookie('test_cookie'));
        $('#gallery').css('background', $.cookie('test_cookie'));
    }

    $('#set_cookie').click(function() {

        var color = $('#set_cookie').val();

        $.cookie('test_cookie', color);
    });

    $('#set_page').click(function() {
        $('body').css('background',  $.cookie('test_cookie'));
        var verifier = 1;
    });

    $('#set_gallery').click(function() {
        $('#gallery').css('background', $.cookie('test_cookie'));
        var verifier = 2;
    });

    $('#set_both').click(function() {
        $('body').css('background', $.cookie('test_cookie'));
        $('#gallery').css('background', $.cookie('test_cookie'));
        var verifier = 3;
    });
});

HTML:

            <p>Please select a background color for either the page's background, the gallery's background, or both.</p>

            <select id="set_cookie">
                <option value="#1d375a" selected="selected">Default</option>
                <option value="black">Black</option>
                <option value="blue">Blue</option>
                <option value="brown">Brown</option>
                <option value="darkblue">Dark Blue</option>
                <option value="darkgreen">Dark Green</option>
                <option value="darkred">Dark Red</option>
                <option value="fuchsia">Fuchsia</option>
                <option value="green">Green</option>
                <option value="grey">Grey</option>
                <option value="#d3d3d3">Light Grey</option>
                <option value="#32cd32">Lime Green</option>
                <option value="#f8b040">Macaroni</option>
                <option value="#ff7300">Orange</option>
                <option value="pink">Pink</option>
                <option value="purple">Purple</option>
                <option value="red">Red</option>
                <option value="#0fcce0">Turquoise</option>
                <option value="white">White</option>
                <option value="yellow">Yellow</option>
            </select>

            <input type="button" id="set_page" value="Page's Background" /><input type="button" id="set_gallery" value="Gallery's Background" /><input type="button" id="set_both" value="Both" />
