What makes the entire script block disabled?
<p>When I check this code in Firebug, the entire block is disabled.</p>

<pre><code>&lt;script type="text/javascript"&gt;

var usercount = 0;
var nbw = '';
$(document).ready(function () {
    $('.alphabet').each(function () {
        _$this = $(this);
        nbw = $(this).val();
        $.ajax({
            type: "Get",
            url: "cfc/basic.cfc?method=CountUsersByLetter&amp;returnformat=json",
            data: "nbw=" + nbw,
            datatype: "html",
            success: function (response) {
                usercount = parseInt(response.substring(0, 10));
                $(_$this.target).attr('title', usercount);
            },
            error: function (xhr, textStatus, errorThrown) {
                alert('errorThrown');
            }
        });
    });
    $('.StartOver').live('click', function () {
        var ReInitAnswer = confirm('Are you sure you want TO DELETE ALL temp dupe records AND start over FROM SCRATCH? \nIt may take a couple OF hours.');
        if (ReInitAnswer) {
            // submit the form TO BEGIN re-creating the temp table
            document.forms["dupeIndivs"].submit();
            //return true; 
        } ELSE {
            alert('canceled');
            return false;
        }
    });
    $('.notdupe').live('click', function (e) {
        alert("indivNum=" + $(e.target).val() + "&amp;SetValue=" + $(e.target).is(":checked"));
        $.ajax({
            type: "POST",
            url: "cfc/basic.cfc?method=SetNotDupe",
            data: "indivNum=" + $(e.target).val() + "&amp;SetValue=" + $(e.target).is(":checked"),
            error: function (xhr, textStatus, errorThrown) {
                // show error alert(errorThrown); 
            }
        });
    });
    $('.alphabet').live('click', function (l) {
        SelectedLetter = $(l.target).val();
        $(".alphabet").each(function (i) {
            var CheckLetter = $(this).val();
            if (CheckLetter == SelectedLetter) {
                $(this).css("background-color", "yellow");
                $('.NameBeginsWith').val(SelectedLetter);
            } ELSE {
                $(this).css("background-color", "");
            }
        });
        $('.Reinit').attr('value', SelectedLetter);
        $('.Reinit').trigger('click');
    });

&lt;/script&gt;
